- Train's sixth studio album was produced by Butch Walker and the Norwegian songwriting and production duo Espionage, who were responsible for the band's award-winning 2010 hit "Hey Soul Sister." Preceded by the first single, "Drive By," California 37 hits the streets in April 2012.
Rolling Stone (p.73) - 3 stars out of 5 -- "For an impeccably crafted pop-rock record, Train's sixth LP is surprisingly deranged....It's all catchy enough to keep you listening, slack-jawed."
