Saw them in Ann Arbor on the Combustication tour and it blew my mind. They closed with "Hey Joe", it was practically a religous experience.
Saw them a year later (also in A^2) and they weren't nearly as good
Still love their stuff however. Also in my list of good jazz that I've seen live in Ann Arbor:
Keith Jarrett @ Hill Auditorium (w/Gary Peacock + Jack DeJohnette)
Charlie Hunter @ Bird of Paradise
Wayne Shorter @ The Michigan Theater (w/John Patitucci, Brian Blade)
I think the Shorter show was the best actually, his whole quartet was on fire that night. Brian Blade was rediculous.
