My brother and I used to watch this series on the local public tv station. If memory serves, it was around 1985. The intro to each show was done by Herbie Hancock. He would announce what style of music would be reviewed for each show, and which known guest musicians would be featured. The cast was three members: a lady with short, dark hair was the show's guitarist (I think her name was Dierdre), they also had a bassist and drummer. Each show, they would cover a certain style of music and break down each element (guitar, bass, drums) showing how the basic feel and playing structure applies to the particular style. For example, one episode was Reggae music. The show musicians would each analyze how to make their instrumental part sound reggae (with chord charts on-screen for guitar and bass). They would also feature guest musician interviews for the various styles and instruments. The Rock School series covered country, rock, metal, funk, reggae, blues, etc. Wondered if anyone remembers seeing the show, or knows anything about it .
