I'm not exactly sure what makes a 21+ festival different than an all-ages fest, but apparently Forever Never Land is the only one in California. Margarita water slides? It's going down near San Luis Obispo all weekend long.
I'm playing on Sunday (1pm) with my homey Paul Oliphant on the drum kit. We will be creating a nice 1920s/future funk vibe in the sun.
Lineup includes RJD2, A-Trak, Goldroom,and Robbie Riverera AND to me the bonus is you get to relive the 90s with Everclear & Vertical horizon (remember them?!).
