At the age of 11, I discovered Led Zeppelin and thought the band was the greatest ever. Nothing could possibly top hearing the first few chords of Good Times Bad Times for the first time. I purchased every album and played them non-stop. At the age of 16, I was given my first bootleg tape of a Grateful Dead concert. Dismissive of hearing Casey Jones and Truckin, I decided to at least give it a listen. Haven't listened to a single Zeppelin album since.
