This, is a pivotal album. Brilliant from start to finish, Kyuss here are perfect, creating an album which has continued to be one of my favorite records since it's release. Thick and oppressive yet with enough space to be absorbed, Sky Valley is more of a spiritual experience than a mere "record". John Garcia has never sounded better, and Josh Homme (who claims to have never really been a Black Sabbath fan) forms the perfect underlying soundtrack for the amazing vocals. I have a lot of trouble describing this album, really only three songs split into separate parts by idea. Really, this is just the pinnacle of the band's existence, and if you have any inkling towards "stoner" rock, this is a must have for your collection.
