Desc: Local DJ: The Story of Flint Rock n' Roll: Directed by Jim Baade. Let's go retro and hear the story of Rock n' Roll Hall of Fame DJ/Promoter -- Peter C. Cavanaugh! Told from inside Flint, Michigan, a blue collar auto manufacturing town just north of Detroit that had a brand of music that was just as tough, gritty and loud as the city it came from. For the first time, now hear the story of Flint Rock n' Roll, that along with Detroit and Ann Arbor formed the 'Golden Triangle' of Michigan Rock n' Roll.
