I'd really love to see more comedy at Coachella. Tim and Eric are doing a kickass looking tour and their show is more suitable than a lot of standup is for the Coachella stages. Maybe even load up on a lot of lesser known standup and put it in another place like a bar area.
At any rate, I'd just love to see more stand-up period. It's a great thing to have to chill out to for a little bit after you've been tripping balls in the hot sun.
