Music is obviously a big deal at SXSW, but where would these indie shows be without the gig posters to advertise them to fans? Presented by the American Poster Institute, Flatstock is an expo that displays work from some of the top gig poster artists of various styles and techniques, allowing fans to meet the artists behind the prints and take home some badass art to hang on their walls. 

Get a SXSW Guest Pass for free to attend the expo, available in advance or onsite at the event (SXSW Badge and Wristband holders do not need a Guest Pass).
