As for Animal Collective live:
I loved them at Coachella. It was like 4:30 when the started, extremely fucking hot, and crowded as fuck. But when Animal Collective opened up with Banshee Beat all the heat melted away and I forgot that I was surrounded by thousands of people. By the time Avey Tare splashed purple paint on himself, I was really into it. Most of the set was new stuff for their next album. It was really awesome to see each song degenerate into a mess of noise and then evolve into the next song. I had a lot of fun watching it.
