South by Southwest (SXSW) — Austin

Held every March in Austin, Texas, SXSW is the world's most important convergence of music, film, and tech. Over 2,000 music acts perform across 100+ venues across the city simultaneously. The film festival premieres major movies, while the interactive conference features keynotes from the biggest names in technology. Many shows and events are free. Austin's live music scene makes it electric year-round, but SXSW transforms the city entirely.
