Like the Beach Boys wrote surf music and never surfed, the members of Nopamine play skate punk and don’t skateboard. They’re too busy working full-time, going to college and playing basement thrash shows to find time to practice 180 kick flips. Guitarists and songwriters Brooks Von Koski and Dan Childs met through mutual friend and bassist Sage Snyder in 2012. They added drummer Aaron Smith last summer and have performed at youth centers, art galleries and house parties. Their set list includes about a dozen originals that may see life as a demo tape sometime later this year.
