The sound quality of this recording is excellent as per the usual from anything I've ever downloaded that Joel has taped (www.jamlive.org has all his shows). We saw the full Perpetual Groove band along with their SICK intelligent light set-up last night at the Vibe in Austin. They dropped "Diamonds on the souls of her shoes" that was equally as beautiful as the acoustic version on this set. The full band incorporates so many of my favorite sounds into their own unique beat. Don't miss these guys when they're in town...it's been hard to work today after having SO much fun last night and everyone I went with feels the same. A rocking groovy dance party that'll leave you smiling....bigger things-are-a-comin' for these guys...
