2) Check out SXSW's site for all the other announced showcases.
4) I'm throwing a free BrooklynVegan day party (11am-6pm) on Thursday March 13th @ Emo's Annex (stage 1) & Emo's Lounge (stage 2), and one the day before at Red 7.
5) I'll also be sending out SXSW-related text messages while I'm there. So will Gorilla vs Bear, Austinist, and Done Waiting. I might say something like, "hey, I just found out Barry Manilow is the secret guest at the Parish tonight. Get there early. There's going to be a line.", or like "Just caught No Wolf Bear Bat Deer Kids over at Red 7. Amazing, and they're playing 7 more shows before Sunday."
