Flory, Andrew: - Andy Flory (Carleton College), a Motown expert, assisted John Covach at UNC Chapel Hill in teaching one of the largest rock history courses in the world. Flory has witnessed the textbook's development--from conception through two published editions--and he has taught rock history to several hundred students in large lecture halls, online sections, and small sections at Carleton. He brings to this edition close consultation with Covach, classroom experience, emerging professional credentials, and youthful vigor.
