The HeartVoice Trio leads the line-up for “Rocka My Soul: A Gospel Celebration” at 4 p.m. Sunday at the Unitarian Church of Baton Rouge, 8470 Goodwood Blvd.

Other local musicians joining the trio will be trumpeter John Gray, sousaphonist and upright bassist Michael Foster, drummer Chris Lee, and pianist Jerrell Gray.

The event will feature a varied program of gospel music.

HeartVoice’s signature sultry Southern sound is driven by the tight harmonies of vocalists Marie Flowers, Helen Hoffpauir and Cathy McManus, whose backgrounds are steeped in Delta blues, jazz and gospel as well as classical music.

Foster is the leader of the multi-genre Michael Foster Project.

A professional trumpet player and educator, Gray performs a wide range of musical genres including jazz, funk, R&B, as well as classical music with various groups including his The JGray Jazz Trio, The Soul Jukeboxx, and The Michael Foster Project.

Drummer Lee is accomplished in jazz, funk, blues, soul and gospel music.

Chicago native Gray is a classically trained pianist, organist, conductor, composer and arranger.
