Here’s a list of 500 confirmed bands for SXSW 2007. Austinist does a great job of rounding up stuff that we post as well as a lot of other sources. We’re lazy, so it’s good to see someone else putting the pieces together.
I always consider this blog more as the constant flow of information and discussion, while you should go to places like Austinist and Showlist Austin for a nice, neat, printable list.
