"Cold Case" goes back to the '70s when the music of Philadelphia was 'killer'. Next week, the team delves into the 1970 murder of a musician who tried to keep his involvement with the Philadelphia Soul scene a secret from his strict preacher father for whom he was an organist.
Meanwhile, Lilly meets her teenage step-brother, Finn. Guest stars include Wesley Jonathan as the victim named Billy, Loretta Devine as a choir girlfriend of Billy, and Anna Maria Horsford as the owner of an after-hours Jazz club. Jamie Hector and Steven Williams also guest star, respectively, as the 1970 and 2009 incarnations of a record label founder.
Written by Ryan Farley and directed by John Showalter, the episode called "Soul" will air on CBS Sunday, October 18.
