The Soulful Strings were an American soul-jazz instrumental group formed in Chicago in 1966. Predominantly a studio band, the project was created and led by Richard Evans, a staff producer and musical arranger with the Chess Records subsidiary Cadet Records.
The group comprised various members of Cadet’s house band – such as Phil Upchurch (on guitar), Charles Stepney (organ, vibraphone), Lenny Druss (flute), Cleveland Eaton (bass, cello), Morris Jennings (drums), Bobby Christian (vibraphone, percussion) and, later, Billy Wooten, in place of Stepney. Sol Bobrov and Bruce Hayden were among the eponymous string players. Other contributors included Johnny Griffith and Donny Hathaway, both on keyboards, and jazz harpist Dorothy Ashby.
