Another is a four piece thrash core band from Syracuse NY http://www.myspace.com/kilimanjaro315.
The third one is a two dozen or so project based in Philadelphia, PA. The group was called together to produce soundtracks to some of Jonathan Olshefski's moving photo essays about the disenfranchised in Philadelphia called Whispers In the Storm (http://whispersinthestorm.com). The group includes various members from many Philadelphia-based bands as well as other friends playing music, video art, collaborative installations, and pot-luck performances.
