Calling All Bands Playing SXSW

I am trying to make a comprehensive list of all the local musicians playing SXSW this year. Half of my job has been made quite easy by the folks at SXSW, who have listed all the official showcases. What's proving to be more difficult is acquiring a similar schedule of all the unofficial free shows, parties, and so forth. I've seen bits and pieces from artists on their MySpace pages, but I'd like more. So here's the deal: if you're playing in Austin that weekend but not as part of an official SXSW show, email me at ghostofblindlemon@gmail.com with the location, date, and time of your show. I will eventually publish a list of the best unofficial SXSW shows.
