In the summer of 1992, White filled in guitar duties at the last minute for Bay Area punk band Monsula, who were performing at Little Rock, AR club Vino's. After the performance, Jason toured as guitarist for the band and eventually relocated to the Bay Area after the breakup of Chino Horde in summer 1993. White joined the Big Cats in 1996, after the temporary departure of bassist Josh Bentley, and took over guitar duties in 2000 after the death of guitarist Shannon Yarbrough. The group is a side project of many musicians, playing live very rarely. Their newest record, "On Tomorrow", was released in 2007.
