I'm very pleased with how they have formatted these lectures. Each 45 minute lecture discusses the composer's life and current circumstances while they had composed the piece, as well as the current music environment that influenced it.
Then the featured piece of that lectures plays through in snippets with pauses to discuss what is being heard and highlights the structural form of each work. It's a great way to break down and highlight each piece especially if you have access to listen to it in its entirety later on.
I really loved Jess Oppenheimer's story of the beginnings and inside workings of the I Love Lucy Show. I could not put it down. There were 3 parts of this audio book. The story performed by the narrator who was very pleasant and easy to listen to, then Jess Openheimer's son did an old time radio play performance of the story (with some great old stars performing), then Jess Oppenheimer in his own voice telling the story - all in a little over 4 hours. Loved each version. CBS thought I Love Lucy was the show that no one would ever want to watch reruns of. Imagine.
