From our friends at Donewaiting.com, deep breath..

We’ve split the list up into two categories: CONFIRMED BY SXSW and NOT CONFIRMED BY SXSW. There is no middle ground.

The unconfirmed list is a mixture of band’s Myspace accounts (a large majority), news articles, e-mails and other shadow sources. Sometimes bands list SXSW but what they really mean is they’re playing Austin while SXSW is taking place. (Keep reading, the list is long as hell)

I’d also like to thank Do512 where I crosschecked a lot of this.
