will get clearance for March 22. The BTO is playing "Cross Pollenization" at the Piano Factory in the South end.
From last year's Phoenix article:
What’s more, the shows are free, so you can come and go as you wish, but Donoso encourages you to “come prepared for a full seven hours of experimental music. There will be a short intermission about halfway through, so people can tear their eyes out, get some food, or just take a break from the music — really, it can get pretty intense.â€
