Howard ferstlers book is a collection of digital recordings. Unfortunately though howard doesn't pay any attention to the performance factor of the musicicans. He just states whether the the CD has good bass, bad bass high treble and the likes. I'm not sure whether this book is intended not for the music lover but the gear freak instead, but sadly I couldn't find anything here for the serious music enthusiast who is concerned with actual musical performance, and not how much thud and tizz a recording has. Basic, and banal.
