By Thom Jurek Three years after the release of its debut Mer de Noms, A Perfect Circle's Thirteenth Step sees the light of day. By that time,Troy van Leeuwen and Paz Lenchantin had left and been replaced by bassist Jeordie Osborne White, formerly of Marilyn Manson, and guitarist James Iha, formerly of the Smashing Pumpkins(though he doe not appear on the album). While van Leeuwen appear on part of the set, guitarist Danny Lohner helped out after he departed. Amazingly, despite the changes, the sound is still very much the creation of Billy Howerdel with the unmistakable vocal of Maynard Keenan from Tool. Produced by Howerdel and mixed by the inimitable Andy Wallace, Thirteenth Step is a moodier, tenser, and more atmospheric (if that is possible) recording than its predecessor.
