The Jazz Ministers Big Band is made up of 18 musicians (5 saxes,4 trumpets, 4 trombones, piano, bass, drums, & vocalists)who find a common spiritual mission in sharing the gift of music through the Christian worship or concert experience. JMBB members are all active performers in a variety of musical idioms and many either hold or are completing degrees in music.

The JMBB draws on a variety of musical selections that are frequently based upon standard Christian hymns and Gospel favorites. Among the selections in the band's repertoire are arrangements by Ralph Carmichael, Chris McDonald, Dean Sorenson, Fletch Wiley, Ed Hogan, and selections from the Brentwood Jazz Orchestra library. Several vocal arrangememts, as well as accompaniments for congregational singing are included in the repertoire. For concert events, the band's repertoire is expanded to include classics from the big band and jazz orchestra genres. The Jazz Ministers Combo is available for worship services and entertainment venues, as well.
