SXSW Schedule Builder

If you're going to SXSW than this schedule builder/helper will help a hell of a lot. If not, then, well, you can see all the bands you're missing. Thanks to this I found out some of the bands I wanted to see are playing multiple times/days. According to the schedule Public Enemy, and Andrew WK are playing, which I didn't know. Also, it listed 'Donovan' on there....Is it the Donovan of Bob Dylan wanna-be fame? I'll look in to it. I know there's even more bands out there not listed, like MSTRKRFT, among others. Know of any good semi-secret/secret/unlisted shows? I get more excited by the day! I hope I can run in to some of you guys!
