Inmates at California's New Folsom prison are slowly creating a sequel of sorts to Johnny Cash's hit record, and if an early preview of one song is any indication, their mix of folk, soul, blues, and hip-hop may be worth the wait. The Prison Music Project, the brainchild of Canada-born singer-songwriter Zoe Boekbinder, is a collaboration between artists on the outside and at least eight men currently or recently doing time at New Folsom, the maximum-security facility adjacent to the lockup where Cash recorded Live at Folsom Prison back in January 1968. Boekbinder, a singer who mixes folk with pop, has released five albums of her own and toured all over Europe and North America.
