This set includes everything ever released by Led Zepplin on LP, and a few single "B" sides as well, including "Hey Hey What Can I Do" - which was worth the purchase of the entire set, as far as I was concerned.Everyone has an opinion on Led Zepplin. Mine is that it's not clear that anything that's come since them in the way of hard, grunge rock has been any sort of improvement over what these guys did. They were the original, and still the best. The combination of Plant and Page is the all-time best in testosterone driven blues and rock.Treat yourself and get this set - it's worth it.
