Secret Treaties is the third studio album and final part of the powerful early '70s trio of albums by Blue ?yster Cult. While the speed-freak adrenaline heaviness and shrouded occult mystery of Tyranny and Mutation is the watermark for the band's creative invention, it is Secret Treaties that is widely and critically regarded as the band's classic. The album spent 14 weeks in the US album charts, Melody Maker rated it "Top Rock Album of All Time" in 1975 and in 2002 Rolling Stone magazine called it one of "The 50 Coolest Records of All Time"
