In 2010, Murphy began working on a project with alternative rock band Weezer's frontman Rivers Cuomo entitled Scott & Rivers. The pair met in Los Angeles in 2010, and soon began writing and recording an album of original songs sung in Japanese. They share lead vocal duties and play guitar in the group. They played their first show at the Countdown Japan Festival in Chiba on 31 December 2012, as the first non-Japanese act to perform at the 10-year-old festival. They released a full-length album, "Scott & Rivers", in 2013.
