The Saltman/Knowles Quintet consists of Mark Saltman, bass; William Knowles, piano; Charles Langford, saxophones; Lori Williams, vocals, and Mark Prince, drums.

Saltman and Knowles met while studying composition at The University of Massachusetts; after connecting with Langford, the seeds of the present group were planted. Later Williams was added as vocalist and Mark Prince came aboard as drummer.

Saltman and Knowles have produced three recordings for various labels under the name SoulService. They have been artists in residence at The Kennedy Center, and earned grants from the D.C. Commission for the Arts. Their latest cd, «It's About The Melody», is available on Blue Canoe Records.
