Marielle V Jackobsons has a very interesting practice: she's part of Date Palms, does live work with bassist Chuck Johnson, and has developed an amazing instrument that she calls a "Macro-Cymatic Visual Music Instrument". She actually was a history of building unlikely instruments - and most of them are focused on vibrations in some interesting way.
If you can't quite imagine what I mean, you should start by checking out her website: http://mariellejakobsons.com/ (click on the big image to get into the site...). You can get a nice tour of her artistic statement as well as a lot of her work; once you see it, you'll want to find a way to see and hear a live show.
With her recent release on the Thrill Jockey label, Marielle delves deeper into the mix of computers and analog systems, melodies and ambiences. It's an excellent release, and has been on constant play here in my hideout. But diving back into some earlier work (Date Palms, the Glass Canyon release) you can find a variety of styles, influences and even instrument use.
A relaxed and enjoyable chat - it was awesome to find someone with so much comfort talking about their process. Enjoy!
