GRÜV-IN lets you join scheduled silent flash mob events. Listen, dance, and enjoy music anywhere, anytime, with as many people as want to join. Events are scheduled by organizers with GRÜV-IN HOST accounts. During our initial roll-out period, host accounts will be limited and exclusive, as will the locations where events are scheduled.
