A Perfect Circle

A Perfect Circle is a rock band that was formed by former Tool/Nine Inch Nails guitar tech Billy Howerdel after recruiting Tool vocalist Maynard James Keenan in the late '90s. Josh Freese, a professional studio drummer and a permanent member of The Vandals and Devo, joined soon after.

The members of A Perfect Circle changed between albums, while many of the musicians still make guest appearances on the records. Maynard James Keenan, Billy and Josh Freese are the only permanent members of A Perfect Circle. The first line up which recorded Mer de Noms was Paz Lenchantin on bass and Troy Van Leeuwen of Failure, on rhythm guitar. When Van Leeuwen left for Queens of the Stone Age and Lenchantin for Billy Corgan's short-lived Zwan, two new members joined for the recording of Thirteenth Step: James Iha of the then defunct but now reformed (sans Iha) The Smashing Pumpkins and Marilyn Manson's Jeordie White aka Twiggy Ramirez on rhythm guitar and bass, respectively.
