The Roots Picnic - Totally fucking awesome. PE backed by The Roots and Antibalas was epic, The Black Keys tore shit up, Antibalas kicked ass, and The Roots closing set (with Gary Bartz!) showed that they can play fucking anything, even Sweet Child O Mine, and still sound great. Sadly TVOTR didn't have very good sound (maybe it was just cause I was far back), and everyone was really just waiting for The Roots at that point, but that's pretty much my only complaint.
On friday was the NINJA tour. I wish NIN had played after, cause their shows are just exhausing. They just put so much into it, and kudos to their sound guy for keeping everything in the mix audible and distinguishable. Jane's Addiction was pretty good too, though everyone seemed a little too drained after the NIN set.
I'd definitely put The Roots and Nine Inch Nails up there with The Flaming Lips as teh best non-Jazz live bands I've ever seen. If you get a chance to see any of them, don't pass it up!
