This year's Austin City Limits Music Festival will take place over two weekends in October, but half the fun will be going on after the sun sets in Texas.

A bunch of artists -- including Beck, Tegan and Sara and Spoon -- set to play the festival have also announced late night sets (official and otherwise) in and around Austin in conjunction with ACL. Check out some of the tweets:

Others scheduled to play after hours include Jenny Lewis, Skrillex, Interpol and Tune-Yards. You can keep up with the late night shows as they're announced on this site.

Pre-sales for members on the official e-list will take place from 10AM-10PM CT on Aug. 21. Regular tickets go on sale at 10AM CT Aug. 22.

Speaking of Beck and ACL, watch him perform on the season premiere of the PBS series 'Austin City Limits' that premieres Oct. 4.
