Hit and miss. Interesting for albums I knew, less so for those I’d never heard of. It also has the drawbacks that come with oral histories—wide variety of voices, inconsistencies, gaps, and a lack of detail. Ultimately, this topic (producing music) is probably better suited for a medium with audio, where the producer/engineer can play examples, compare and contrast different takes, etc. Reading about how good, bad, or indifferent something sounded only goes so far.
