During a very rare performance at Los Angeles' House Of Blues last night, Chance the Rapper brought a special surprise with him on the west coast. Chance crushed the performance as he rocked a soled out for night 15 of Red Bull Sound Select's 30 nights of concerts in Los Angeles. Chance delighted fans by bringing out Big Sean to perform his DJ Mustard-produced single 'IDFWU.' Watch the video above as we wait on new music from both parties before the end of the year.
