While there still remain questions as to who will be replacing the Beastie Boys at this year’s Austin City Limits, the same can not be said about the festival’s late night entertainment. Today, the Austin, Texas based festival, scheduled to take place from October 2nd and 4th in Zilker Park, unveiled its official 2009 aftershows.

Thursday, October 1st offers a pretty stellar pre-show with The Walkmen and Blitzen Trapper hitting Emo’s, while Friday is jam packed with the likes of DevotchKa, STS9, !!!, and The Raveonettes. Highlighting Saturday night’s festivities will be Thievery Corporation’s performance at Stubb’s and the indie mayhem of Grizzly Bear and Beach House at Emo’s. The final night will be a bit more subdued with only two aftershows scheduled, though both are easily must sees — Ghostland Observatory will take to Stubb’s and Bon Iver will look to cap things off at the Paramount.
