→ SUBSCRIBE TO BOILER ROOM: br br Last Wednesday, Ray Ban and Boiler Room took over Empire Garage in Austin for one of the most buzzed-about shows at SXSW 2015. Flex was in the building to introduce Dipset and the boys from Harlem shut it down with a legendary performance of "Oh Boy", "Hey Ma", and "I Really Mean It" (look out for that Just Blaze cameo) among other classics. Historical night.
