As someone with an extremely limited knowledge of music I have always felt intimidated by classical compositions. I could not tell you the difference between a symphony and a concerto, but after listening to these lectures I have a much better appreciation of them.
The lecturer's delivery is a cross of Lewis Black and George Will--authoritative but wickedly funny. He actually made me laugh out loud a few times. His passion for these works comes through in every lecture.
The format he follows is a brief bio-sketch of the composer followed by snippets of music and commentary. When he says "notice how the composer uses dissonant harmonies to convey struggle" you can actually hear it. Each lecture is meant to be complete in itself allowing you to jump around, but I found listening beginning to end to be most convenient.
This is an ideal work for an audio book.
