Treasure Island Music Festival isn't the easiest site to get to—fans are shuttled between San Francisco and the island that sits right off the Bay Bridge—but it's worth the trek. This year's two-day event (October 19-20) featured Robert Delong, Beck, Haim and Phantogram rocking two main stages, while a silent disco kept it chill with DJs like Shouts!, 8ball and Vin Sol. Bonus treats included food trucks, mural painting, ukulele lessons and bubble launching. Both days drew record crowds, and it's easy to see why from these highlights captured by photographer Gil Riego.
