A giant festival held in Austin, Texas, during Spring Break. It is comprised of Music, Film, and Interactive showcases. Generally, it is a week of crowded bars, free stuff (and often free alcohol), thousands of concerts, afterparties and no parking. Although it is held primarily downtown in clubs and bars, many coffee shops, clothing stores, back alleys, and parks also turn into packed music venues.
I wanted to buy a SXSW wristband, but then I realized I could get into half of the shows for free anyway!
