Treasure Island Music Festival is an annual two day music festival that takes place on Treasure Island, California, located in the San Francisco Bay. The festival is produced by Noise Pop and Another Planet Entertainment . The first day of the festival consists of Electronica and Hip-Hop/Rap influenced performers while the second day consists of Rock and Indie rock influenced performers. Each day the sets are split between two separate, nearby stages, however the performances are staggered such that attendees can listen to every performer. Typically, the northernmost stage is the main stage on which the headliner plays. The music festival is noted to be rain or shine. Although the weather in the San Francisco Bay Area is typically mild, rain and wind in autumn is not uncommon and poses a challenge to both attendees and performers.
