So to make it short, this LP is really awesome though the work well when it was first came out not so popular because too harmless (Complete Plötzinn) but who wants to hear really good rock music is best here! Led Zep at its best and better than the last 3 LP`s which has brought out the best rock band in the world, here were all still motivated and not drawn from rock'n'roll Lotterleben!
