According to Ludo's MySpace, it's playing SXSW on a bill on March 13 with: Bowling For Soup, The Presidents of the United States of America, Zebrahead, Wheatus & Army Of Freshman.
F5 Records also checked in to say that Earthworms and Nato Caliph will be doing at least a day party -- and possibly more.
Really, at this point, who won't be there?
