Transcriptions and tracks from more than 30 years of interviews, and recorded footage. These TABs and tracks deliver accuracy and insight into the music of Led Zeppelin. The book includes complete music notation and TAB transcriptions to eight Led Zeppelin songs. 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. Titles: Black Dog, Communication Breakdown, Dazed and Confused, Heartbreaker, Immigrant Song, Rock and Roll, Since I've Been Loving You, Whole Lotta Love.
