Really great interpretations of leading, historic bass players. Very good quality recordings and transcriptions. You really get a feel for the players style and they have amazing players - none more so than the great James Jamerson. Well thumbed. I learnt to play all the lines except one. I don't think I can ever let this book out of my collection. Can't wait to have time to go back to it. If you can get a portable bass amp (like the Pandora Px5D) so you can hear your playing and the CD examples together over headphones/speaker, I copied them onto my ogg/mp3 player.
