Last week on "The Traitors," the Faithfuls caught their second Traitor as Boston Rob Mariano was banished from the game.

Headliners scheduled to lend their talents to the proceedings include punk pioneers Green Day, rising folk hero Noah Kahan, emo icons Fall Out Boy, hitmakers Weezer and indie vets Vampire Weekend.

Oceans Calling has officially announced this year's lineup, featuring Green Day, Noa Kahan, Fall Out Boy and more!
