Isaiah began in 2001 as the Saturday night Rock & Roll praise team for Jubilee Christian Center in San Jose, California, under the name of Holy Smoke. Jubilee is a 15,000 member Pentecostal church, which features gospel-style worship led at the time by Ron Kenoly. Shortly thereafter, members of the band also began helping out at City Christian Church, San Francisco, a church plant partnership between Jubilee and Phil Pringle’s original church in Australia.

During this time, the band began ministering at drug and alcohol rehab groups as well as performing at fairs and festivals. Later, the band also began its prison ministry, with performances at Elmwood (Milpitas, CA), San Quentin (Larkspur, CA), Santa Rita (Pleasanton, CA), and youth correctional facilities including Camp Wilmont Sweeney (San Leandro, CA), Hillcrest (San Mateo, CA), and others.

With personnel changes and the expansion of its ministry focus, the band changed its name to “Isaiah”, and is no longer associated with Jubilee or City Christian Church. The band now consists of members from all around the San Francisco Bay Area, representing churches from South San Jose and the Peninsula, to the East Bay and Livermore.

Isaiah’s primary focus continues to be recovery ministry, and the band regularly performs at ministries around the Bay Area, including Higher Power (Foster City, CA), R&R (Palo Alto, CA), The Bridge (Palo Alto, CA), and many others. The band also continues to do prison ministry, festivals, and church worship services, and occasionally travels out of the Bay Area for special ministry events.
