Even though Electric Mustache will not be at this years SXSW festival in Austin (again) the state of Arizona will be strongly represented. If you are going to be in the Austin, TX area on March 19th you can check out I Heart AZ "the official unofficial Arizona SXSW party" being presented by Max3 and Phoenix New Times.
Check out the full and official schedule here for a list of all the bands, local and otherwise, playing SXSW. The SXSW website was also nice enough to put up some mp3s for you to download.
Here is just a sample of some of the awesome AZ bands that will be there:
Miniature Tigers - "Cannibal Queen"
The Silos - "Behind Me Now"
What Laura Says - "July 23"
Dear and the Headlights - "I'm Not Crying. You're Not Crying, are you?"
Golden Boots - "Country Bat High II"
