San Francisco’s Spiritual Cramp/Spy/World Peace-related, no-distortion-pedal-using hardcore band Fentanyl kicked off a tour with Mexican Coke, their Houston-based Convulse Records labelmates known for wearing ski masks and waving a shotgun around on stage, plus Asbestos, and apparently things got messy for Mexican Coke at the Salt Lake City show over the weekend (10/5).
