“Rock ‘n’ roll is a participatory sport,” Steven Van Zandt famously said, a member of Bruce Springsteen’s iconic E-Street band. “It ain’t passive. It ain’t TV. Go out there and rock ‘n’ roll and dance and have fun.” Street art’s a participatory sport too, with all the messy nuance an active involvement with life entails. LA-based Muckrock has known this since long before she became the internationally known street artist she is today.
