Limited edition of 1500 individually numbered copies on purple coloured 180-gram audiophile vinyl. Secret Treaties is the third studio album by American rock band Blue Öyster Cult, released in 1974. It features the same band members and production team as their previous album Tyranny & Mutation, but also the only BÖC album that does not feature a track with lead vocals sung by guitarist Donald “Buck Dharma” Roeser. Lyrics to the lead-off track “Career of Evil” were written by future punk poet Patti Smith, a longtime contributor to the band (and, at the time, girlfriend of BÖC keyboardist and rhythm guitarist Allen Lanier).
