Rated 10/10
Their equivalent to The Beatles White Album, a long double album that's a little incohesive as it feels like all manner of shit was thrown to this particular wall to see what would stick, where the highs are so so so good ("Trampled Under Foot", "Houses Of The Holy", "Kashmir", "In My Time Of Dying", basically all of disc 1), but the lows are pretty meh ("Down By The Seaside", "Night Flight", "The Wanton Song", "Boogie With Stu", "Sick Again", basically all of disc 2). But it's Led Zeppelin so you can forgive most of it.
