A Perfect Circle formed in 1999 from Tool band members Maynard James Keenan and Billy Howerdel which came to include many other member throughout it's history such as members of Smashing Pumpkins, Ashes Divide and Puscificer.

Being somewhat of a supergroup in the rock world, the band had to take a brief hiatus in 2004 to work on other projects but has since said to have been working on new material.

A Perfect Circle has released three albums thus far. "Judith" is one of their more popular songs on rock radio you might have heard. Any fan of Tool, is sure to love this group!
