Edgetone New Music Summit

Last week, I had the opportunity to attend the Edgetone Music Summit, including the Wednesday night performance SonicLight. All the performances including both musical and visual elements being “performed.” The visuals were as much a live performance element as the music, rather than simply films or videos that were being shown while the music was played.

The first set was a piece by No More Twist! entitled Inquisition for Suspect, Examiner and Audience. No More Twist! is the due of Les Hutchins and Polly Moller, who of course should be quite familiar to regular readers of this site.

The performance involved Polly Moller, as the “Suspect”, being attached to the Glove of Truth, a custom lie-detector that measures vital signs and transmits the data to a computer, where it is interpreted visually and sonically, and used to determine falsehood or truth, as in the sample below:

Audience members were invited to ask yes/no questions to invoke declarations of “true” or “lie.” This is of course especially fun for audience members who may be able to independently verify the answers to their questions. Of course, the most fun for everyone was when the word “lie” would appear on the screen in all its accusatory grandeur.

The next performance was by Kwisp, a duo featuring Walter Funk and Lenny Bove. It featured a variety of elements including a holographic projection that audience members were encouraged to come view at close range (but not too close lest one damage the specialized lens); and custom analog electronics including the tower electronique, displayed to the right.

Musically, Kwisp was closer to the standard “experimental electronics” performances that I perform or attend, with its combination of laptop-based electronics, analogue synthesis and processing, improvisation and noise.

The final performance was a video and live-music set by Thickness/Mono-Layer. The group, which includes John Reily, Eric Steinberg and Charles Kremenak, performed a “power duo” of bass and guitar (with synthesis and processing) against two videos projected on either side of the hall. The videos were incredibly detailed in their editing (several of us commented on the sheer volume of separate clips and cuts and the amount of time it must have taken to put them together). Indeed, I was quite involved in the visuals, that I didn’t spend as much attention on the music, though I did recognize the guitar synthesizer at various moments.

The Edgetone Music Summit is an annual festival in San Francisco that features “Independent artists most of whom are practitioners in music and sound of improvised and or experimental and or exploratory nature.” It began as an event to support the artists of Edgetone Records, an artist operated recording label for improvised and experimental music that includes several of our friends. As part of the summit, I had the opportunity to hear a lecture by Edgetone Records’ founder Rent Romus on the concept of the “Artist Run Label” the night before the SoundLight performance.

The programs provided for the summit each included a “drop card”, which can be used to download music by each of the performers from all events of the festival. We will be listening to, and probably commenting on, some of those tracks soon…

Carnival of the Cats #228

Welcome to the 228th Carnival of the Cats!

So follow Luna’s lead and find a comfy spot to enjoy the round-up of cat articles from around the blogopshere…

We begin with a moving tribute in photos and poetry to to Spike at Watermark. His “contributes” both funny and touching are explored in verse. He was to be helped to the rainbow bridge, but he rallied on Friday, with purrs and lap time. We all hope for the best.

It’s the Battle of the Cutest over at the House of Chaos, with images of “fractional cats” and the adventures of the house’s only female feline denizen, Frankette. “Oh sweet little kitty-cat…right ?”

We of course love black cats. But what is even better? Black on black! Blog d’Elisson presents this black neighbor blending into the kitchen table. Also, the Mistress of Sarcasm visits the barn and says hello to a cute feline resident.

Over at Conservative Cat, Lucky the fearless cat does battle with a remote-controlled helicopter. I don’t think it went all that well for the helicopter.

It doesn’t look like things are going too well for this cricket either. Kismet is the mighty bug hunter at TacJammer. There is know evidence that he ate the cricket, but one can only speculate from the circumstantial evidence…

Photographing cats can be quite a challenge. But once in a while a photo comes together perfectly, as in the case of this Abby from Manx Mnews.

Photos like this (and of course some of Luna’s many portraits here at CatSynth) remind us of animals’ natural beauty, which Debra contrasts to human vanity.

More expressive photos of a different sort at Lab Kat, where the feral kittens are displaying some serious ‘tude.

Dude, s’up?

Smokey does his impersonation of Monorail Cat at composite drawings. We’ll leave the interpretation of his other photo as an exercise to the reader…

Chance displays a little bit of tummy, but “a hole lotta Man-Cat cyuteness.” [sic]

Gree displays a little bit more at the House of the (Mostly) Black Cats.

Aloysius enjoys some patio time while the painters take the weekend off at Catymology. Looks like fine way to enjoy the afternoon.

Meanwhile, we have the relaxing symmetricats at Elms in the Yard.

While the cats at Mind of Mog may not be as symmetric, they do know how to share. And we have another tummy shot from Meowza as well.

Snow, Leo and Fairy have a new home at Purrrrs.com. That’s with four R’s. If you miss one of the R’s, no fluffy white kitties for you! Yes, the internet can be a very unforgiving place sometimes.

Contrasts in activity are the topic at StrangeRanger, While Maddie “goes to town on her catnip squirrel”, a nap is about as much action as one gets out of Ivy.

Want more action? Check out the Cat Attack at The Scratching Post.

Willow and China Cat show off their expressive eyes for the Bad Kitty Cats Festival of Chaos. You can see black-and-white versions of each photo as well.

Samantha and Tigger are having a BBQ on the beach today. Looks like fun (and that BBQ is looking tasty).

More weekend fun. Tiny relaxes surrounded by English Ivy, while Babe inspects the detritus of a recent fence and stone-wall project. Visit them both at sisu.

The “Cat Boys” Kashim and Othello are tired out from helping Astrid host yesterday’s Weekend Cat Blogging. So they are taking it easy on the balcony today.

Actually, that sounds like a pretty good idea. I’m going to go take my coffee out to the balcony and relax for a bit, as it seems we have reached the end of this week’s Carnival of the Cats. Thanks to all who participated!


Weekend Cat Blogging: What Did You Eat?

Our friends Kashim, Othello and Astrid are dedicating Weekend Cat Blogging to our fellow cat blogger Sherry “Sher” Cermak of What Did You Eat?. She passed away suddenly last Sunday.

Sher was also an accomplished food blogger, and we have made some her recipes before. So in addition to Weekend Cat Blogging, we are also participating a tribute hosted by the “Bread Baking Babes” this weekend and preparing her last recipe.

So let us move to the kitchen and dining area of CatSynth HQ:

And with Luna ready to supervise, let us begin:

Angel Hair Pasta With Red Pepper Pesto

[Adapted from Food and Wine.]

3 medium red bell peppers or bottled roasted red peppers
1 tablespoon pine nuts
1 small garlic clove, smashed
1/4 cup basil leaves, plus 2 tablespoons chopped basil
1/4 cup extra-virgin olive oil
Salt and freshly ground pepper
1/2 pound angel hair pasta
1/2 cup grated pecorino cheese

Roast the red peppers over a gas flame or under the broiler, turning occasionally, until charred all over. Transfer the peppers to a bowl, cover with plastic wrap and let cool. Peel, core and chop the peppers. (We opted for the bottled peppers here at CatSynth.)

In a small skillet, toast the pine nuts over moderate heat until golden, about 4 minutes. Let cool.

Transfer the peppers and pine nuts to a blender or food processor (If your food processor has been sitting in a box at the bottom of a kitchen cabinet since moving, make sure to clean it first.) Add the garlic and whole basil leaves and blend until coarsely chopped. Add the olive oil and cheese and puree to a chunky pesto. Season with salt and pepper.

In a large saucepan of boiling salted water, add the pasta and cook until al dente. Drain and cool slightly under running water. Transfer the pasta to a bowl and toss with the pesto. Season the pasta with salt and pepper. Top with the chopped basil and pecorino and serve at room temperature.

Now let us raise a glass and toast…


More tributes can be found at Weekend Cat Blogging, hosted at Astrid’s food blog. I’m sure the boys won’t mind too much.

The Carnival of the Cats will be hosted here at CatSynth tomorrow. Click here to submit your entry.

The Bad Kitty Cats Festival of Chaos will be hosted this week at Pet’s Garden Blog.

And of course the Friday Ark is at the modulator.


The Fourier Transform of a Cat

We at CatSynth never miss an opportunity to combine mathematics and cats. Recently, our friends at Walking Randomly posted this image:

It was created by Andrew J. Bennieston, and inspired by this comic from xkcd:

Unlike the number theory and other mathematics we like to post here at CatSynth, the Fourier Transform is part of our stock and trade. There are many variants, including the Discrete Time Fourier Transform which one of the basic tools of signal processing and sound synthesis:

Basically, what a Fourier Transform does is decompose a signal (or any time-varying mathematical function) into separate frequencies. If you have a spectrum representation of a sound, this is output of a Fourier Transform. Similarly, if you have a graphic equalizer on your stereo, it can be seen as operating on a very low-resolution Fourier transform, as it allows one to raise and lower different frequency ranges of sound.

For images, “frequency” corresponds to detail. Highly detailed areas of image that change from pixel to pixel are high-frequency, while areas of constant color or intensity are lower frequency. Another variant of the Fourier Transform, the Discrete Cosine Transform, or DCT, is more often used with images because it tends to put more information in lower frequencies.

Theoritcally, one should not lose any information when taking a Fourier Transform of a signal (or image) and taking the inverse to retrieve the original. However, in Bennieston’s image, which applies two DCTs to the original image, results in the “ghost” that loses a bit of the original detail. Certainly, some is due to the rounding error when doing any calculations on the computer, but it seems like more than that. Most, likely, the DCT is more sensitive the boundaries, i.e., what happens at the beginning or end of a signal.

DCTs are often used in “lossy” image and audio compression, such as JPEG for images. However, I have rarely seen them used in music applications, where one tends to see more general Fourier Transformations, which correspond more closely to an intuitive understanding of musical frequency.

As such, it would be interesting to work with DCTs in a musical context and see what transpires. If we ever get around to this project, we will certainly post it here on CatSynth.

This post is part of the Carnival of Mathematics which is being hosted this weekend by Logic Nest.


Sad news today

Some very sad news today. Our friend sher of What Did You Eat? passed suddenly this morning.

Sher was one of the first people we met through Weekend Cat Blogging. She often left kind words on our site for Luna, whom she quite admired. And in turn we got to know her late cats Upsie and Sundance, and of course her little black kitten Laura.


We remember her sharing life with cats and squirrels. But she was also an accomplished food blogger, and we have tried several of the recipes she posted. Indeed, I was going to be making the Angel Hair Pasta With Sweet Red Pepper Pesto that she posted on Thursday, not knowing this would also be her final post.

Our thoughts are with Sher’s family and friends this evening.


Weekend Cat Blogging #163

It’s time for the Weekend Cat Blogging #163 round-up:

Luna will supervise the festivities from one her high perches.

Thanks to everyone who wrote in to wish us a happy second anniversary of CatSynth. And with that, let us begin…

Breadchick threw out her back lifting some heavy amplifiers (another reason why we at CatSynth prefer software for our audio work). But fortunately, LB is there to look after his mom. Breadchick is in the pro-audio business, so maybe she will come visit us at CatSynth while recovering for music, audio and feline fun. Oh, and that New England breakfast is looking pretty good this morning…

We move from pro audio to Music and Cats, where Sergei is puzzled by the behavior of his siblings Sasha and Lyra. They have been fighting a bit, and Sergei doesn’t understand why he can’t curl up with them for naps. “Sergei’s a lover, not a fighter, so he gets out of Sasha’s way, and looks to his people for affection.” We at CatSynth wish more humans were like that.

Things are more peaceful at Rosa’s Yummy Yums, where Fridolin has been an angel and doesn’t even mess with Maruschka. “He can be such a loveable cuddly kitty when he is not behaving like an evil little ‘monkey’!

More feline friendliness can be found at Sammawow, with some great “then and now” photos of China Cat and Willow napping. It is great to have some constants in life, like the setting for these naps, that one can return to for years.

Napping appears to be activity of choice this weekend (and perhaps most weekends). And there is a serious snoozefest at CorgiFeathers featuring Titania and Oberon. A Midsummer’s Night Dream, anyone?

A little more activity can be found with Chica and Pumuckl, who are pretty intent on something on their ceiling. You will have to follow the link to find out what it is…

Our friends at the House of the (Mostly) Black Cats share some pictures of the friends (or rather, pikshurs of furrends). There was a little bit of difficulty with a disposable camera, and apparently much cursing (by their mom) as a result. But they still have some great pictures to share.

Our friends Samantha and Tigger are hosting the Bad Kitty Cats Festival of Chaos this weekend. The theme is “Christmas in July.” Now if it only it was Channukah in July…

Time for some WCB Apocrypha!

Arthur and the other cats at Gattina’s are mouse hunting. Fun all the whole feline family.

Of course, it wouldn’t be Sunday without Lectionary Readings from LOL Cat Bible.

We were happy to receive wishes from our house-panther friends, including Mickey the Black Cat.

And Mr. Hendrix.

And that concludes the round-up for now. As always, we will continue to post entries as we receive them through Monday morning, so all are still welcome to participate.
