You’d swear half the town of Waialua, Hawaii showed up to party with Onward, Etc., Black Square and Serpico & the Sinners for a raucous backlot hoedown on Oahu’s North Shore this past January. Go jumping off buildings in Waikiki, witness a beat-for-beat hip hop producer battle and get down and dirty with punk rock power trio Rats in Honolulu’s Chinatown in this latest episode of B-Side HNL.
