We had a blast (ahem) Saturday night at the Yuri’s Night party at NASA Ames Research Center; stay tuned for video and more, including the results of the Futuristic Musical Design Challenge. But that’s no reason the party has to end. If you’ve listened through all 55 songs on the 45 Tribute and want still more music, Amon Tobin and Deru have kindly donated music mixes for the yuricdm.com minisite. It’s good listening to pick up your week:

Exclusive Free Mix: Amon Tobin, Back from Space

Exclusive Free Mix: Deru

And here are the direct links to listen / download:

Updated! If you were having problems with the links, it’s because I made a mistake generating URLs with Amazon S3, and some browsers (IE and Safari but evidently not Firefox) get picky. It should be fixed now.

For more on Amon Tobin, our friends at Current TV have this interview on the Foley Room album — not exactly news, but inspiring stuff, nonetheless. Anyone who’s a found sound sound design fan (as I know many of you are in your own work) should get a kick out of it:

Let us know what you think of the music in comments. (Truly — thoughtful criticism is welcome as well as praise.)

Hello from Ground Control: this week, I’ll be coming to you live from CDM’s micro-blog for Yuri’s Night Bay Area, ground zero for the global space rave celebrating human exploration of the cosmos. CDM’s challenge: to bring all the goodness up close and personal to you, from California to wherever you are on Planet Earth.

Watch the minisite now, during the event, and in the couple of weeks following at:

Yuri’s Night needs special nerdster love for a number of key reasons — a huge lineup of music, art, and science, plus a special CDM event and booth:

• Music: The likes of Amon Tobin, Tycho, Christopher Willits, and many others … and our friend Ganucheau, too
• Motion: Interactive installations and visualists everywhere, including our man Joshua with his incredible Wii-powered SuperDraw, built with Processing
• Space and Science and Games: Here’s where I get especially excited — it’s an event on the airfield at Ames Research Center, not typically a place non-NASA employees can go, and we actually get to play there and listen some of the world’s top scientists. And Will Wright (creator of SimCity, Sims, and the upcoming Spore with its generative music) will be there, too, just in case your geek circuits weren’t overloaded yet.
• CDM @ the Hangar: We’re running a special Futuristic Music Design Challenge competition, and we’ll have the CDM booth for much of the evening where various musical / visual makers will be showing off their inventions (with more of our friends elsewhere at the event). So stop by and say hi.

As an addendum to why trying to make computer models musically creative can be so disastrous, maybe the problem is we fail to understand what creativity is.

Scientists funded by the National Institute on Deafness and Other Communication Disorders (NIDCD) have found that, when jazz musicians are engaged in the highly creative and spontaneous activity known as improvisation, a large region of the brain involved in monitoring one’s performance is shut down, while a small region involved in organizing self-initiated thoughts and behaviors is highly activated.

That’s just one study, and I won’t pretend to be an expert in neuroscience. But what the scientists are describing is awfully close to the nuanced way jazz musicians will describe improv. It’s not not thinking. But it’s also not self-monitoring. It’s something else.

Hearing over the din of noise is something that humans do a lot better than computers. A new mathematical technique promises to provide highly accurate models of sound, even with broadband noise in the picture. Why does this matter, aside from mathematical curiosity? For one, better sonic analysis could mean more realistic models of instruments and more flexible sound editing tools, inspiring a new generation of music software.

From our friend kokorozashi:

‘In a recent issue of the Proceedings of the National Academy of Sciences, Marcelo Magnasco, professor and head of the Mathematical Physics Laboratory at Rockefeller University, has published a paper that may prove to be a sound-analysis breakthrough, featuring a mathematical method or “algorithmâ€Â? that’s far more nuanced at transforming sound into a visual representation than current methods. “This outperforms everything in the market as a general method of sound analysis,â€Â? Magnasco says. In fact, he notes, it may be the same type of method the brain actually uses.’

This certainly wouldn’t be the first time new algorithms yielded scientific advances and musical advances alike. Even the famed (or infamous) AutoTune plug-in benefits from data processing techniques used in oil exploration. (Lesson: it takes a lot of science to make Jessica Simpson sing in tune. Sorry, couldn’t resist.) Of course, the converse is true, too: better sound processing can be very useful to a broad range of sciences, because, well, sound is just about everywhere.

[Updated] Tom Duff has managed to hunt down the actual paper so you can get this straight from the source:

While I wouldn’t normally say this of academic papers, it has really pretty pictures. (Seriously: visual renderings of the analyses not only illustrate the point, but also happen to look gorgeous.)
