During a stint at the South by Southwest music festival in Austin, TX, Allister met and became close with Japanese rock band Ellegarden, and they were soon invited to a two and a half month/ 40 date tour of Japan together in 2006.

[5] On this tour, Allister released the album Guilty Pleasures, on which Murphy sang most of the songs in Japanese, and the CD went on to sell over 250,000 copies.

[6] The following year, Allister member Tim Rogner found out that he was to become a father, and the band announced their intention to go on hiatus, but resumed activity again in 2010.

[13] The pair share lead vocal duties, and released a 12-song album of original songs sung in Japanese on March 20, 2013 through Universal Music.

Murphy also joined Weezer on stage at the Punk Spring '13 festival in Tokyo, Osaka, and Nagoya to play Scott & Rivers first single,"Homely Girl."
