This year, 89x have organized two whole nights of indie and alternative for their highly anticipated Christmas blowout. Awolnation headline the first evening on Friday, Dec. 18, still hot off the success of their massive 2014 single “Sail.” Intense, female-fronted, and forward-thinking acts Metric and Pvris also appear on the bill. The following night’s festivities on Saturday, Dec. 19 should prove considerably more chillaxed, owing to headliners Sublime with Rome. Bust out the Christmas trees for their stoney new jam “Wherever You Go.”
