Without sounding overly dramatic, that DVD changed my life. I still remember the day me and a friend were browsing around at a Best Buy in 2004 and I made the one of the best purchases of my life. That day I went from being a fan who had most of the studio albums to being a die-hard, collecting every live recording, book, magazine etc. I could get my hands on. I never understood what was so great about live music until I viewed it. They way they improvised, added parts, the medleys, was a revelation for me. I literally wore out that copy and purchased another a few years later, and wore that one out as well!
Led Zeppelin DVD=The greatest piece of media ever released.
