Ultimate Bass Play-Along Led Zeppelin, Vol 1 by Led Zeppelin

(Guitar TAB) All new transcriptions and tracks drawn from more than 30 years of documentation, interviews, and recorded footage. These TABs and tracks deliver unprecedented accuracy and insight into the music of Led Zeppelin. This book includes complete music notation and TAB transcriptions to eight Led Zeppelin classics.

There are two versions of every song on the included CDs: an instrumental sound-alike recording, and an instrumental accompaniment track (without bass) so you can play along. When you use the CDs in your Mac or Windows-based computer, the TNT (Tone 'N' Tempo) Changer lets you easily loop sections for practice, slow tracks down or speed them up without changing the pitch, change the key, and switch back and forth between full instrumental and accompaniment tracks.

The tracks are just fine- well-played- and the tabs easy to read. The included CDs have the complete instrumental tracks for all the songs included in the book. The sweetest feature is that you can slow each of the tracks down to listen or practice at a leisurely pace, and build up speed as you get better. You can also alter the key a bit, if you happened to tune your bass differently.
