Zoe, you'll be happy to know that one of the experimental groups, "Breccia," includes a cellist, who will be playing at the pre-festival art show opening on Thursday, and the Saturday of the festival. I met her today. They will be performing two pieces on Thursday, "Ornamentik" and "Stones", and a piece on Saturday called "Crossings" by Alvin Lucier. Below is her description of the first two:
"Ornamentik" consists of a number of sustaining instruments (depending on who can make it that night, we'd have: clarinet, melodica, cello, violin, organ, and flute) playing a G in unison. Then, looking at the score (a dozen or so abstract design images), each musician ornaments the G whenever s/he feels it appropriate--the idea is to interpret the images into sound.
"Stones" is just that--a group of musicians "playing" stones by striking them together to make sounds. We've been batting around the idea of placing the stones on a miked table or board so as to amplify the sound, but that hasn't happened yet. It's very abstract, but given the right attitude (on the part of both performers and listeners) can be transcendently beautiful."
