What shows/venues should I RSVP to for SXSW music festival?

You can go to this website http://do512.com/c/sx2010/bands and it has lots of shows (free and RSVP). Some of the RSVP's have a lot of people already so you might need to get to those early. It's my first time going so I'm still trying to put my schedule together! Also if you have an Iphone there's a SXSW app that has all the shows listed and is very helpful. Have fun!!
