One of my favorite bands for the last few years has been Sound Tribe Sector Nine (STS9). I have had the pleasure to enjoy more than a dozen of their shows (maybe more), since I first saw them open up for the String Cheese Incident (SCI) during the summer of 2000 at the Red Rocks Amphitheater. My most recent experience was shortly before the new year on December 29 in Atlanta.
Check out a four minute video on CNN about the band's charity work. I did not realize the full extent of their work. My own experience has been limited to donating food at their shows, since at every show they collect canned food for that city. This is done for at many of the shows I attend and is coordinated with Conscious Alliance.
