For those of us who are too young to have experienced Zeppelin live (or never got a chance to), this album is essential. It gives the listener the raw power of Led Zeppelin in their early years. Also, this album has a couple of songs that were never released and abstract, long versions of Zeppelin classics such as an 18 minute Dazed and Confused. If you love Zeppelin like I do, buy this album. It gives one a different, less refined version Led Zeppelin.
