Rich Kids on LSD (R.K.L.) was a Californian hardcore punk band formed in 1984 in Santa Barbara, California. They were associated with the "Nardcore" scene that evolved out of nearby Oxnard. Their music expanded over the years from pure West Coast hardcore to an extraordinary mix of hardcore with rock elements. This style, along with touring, made them very popular on the European scene, especially among skaters in the eighties and nineties.

Their musical evolution can be heard on their webpage, which features "RKL Radio" with nearly all of their songs streamed including a complete discography.
