S6·E10 Blues (aka Hard Rock)

Stu Gorman is a music-industry figurehead for the Syndicate. He and his financial expert, Belker, are taking control of the music industry and the IMF have to stop him. The IMF know that Gorman killed a witness, Judy, to keep her from testifying, so Barney auditions for Gorman using a song called ""Judy's Gone Now"" and claiming Judy had taped Gorman when he killed her, and he has the tape. Barney gets Gorman to pay blackmail while Willy fake-rigs Belker's car to explode and claims he's working for Gorman when caught. Belker gets lead to Jim as a corrupt policeman with the recording, and he and Jim agree to blackmail Gorman instead. The IMF gives Belker a fake tape of the murder scene and when Belker confronts Gorman, Gorman knows its a fake and admits he killed Judy, then tries to kill Belker. But the police show up - the IMF have Gorman's confession on tape.
