No need to speculate anymore. Another Planet just announced the official lineup for the 3rd Annual Treasure Island Music Festival on October 17-18th. Once again, it's got a little something-something for everyone. Day one serves up dance/electro highlighted by MGMT + Passion Pit and day two caters to the indie/rock crowd with our faves The Walkmen + Grizzly Bear.
