2This book contains complete, authentic drum notation and play-along tracks to eight Led Zeppelin classics. There are two versions of every song on the included recording: an instrumental sound-alike recording, and an instrumental accompaniment track (without drums) so you can play along. Also included is TNT (Tone 'N' Tempo) Changer software, which 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.
