American rock supergroup A Perfect Circle was formed in the late 90s by Tool vocalist Maynard James Keenan and former Tool guitar tech Billy Howerdel. On their debut, Mer de Noms, A Perfect Circle were seen as an extension of the alt-metal-fused-with-art-rock style popularized by Tool in the early to mid-'90s. Despite comparisons, however, A Perfect Circle quickly developed into its own entity, focusing on lighter and more melodic sounds that were combined with a theatrical, ambient quality incorporating occasional strings and unconventional instrumentation on later albums like Thirteenth Step and Eat the Elephant. Over the decades, members of Nine Inch Nails, Marilyn Manson, Smashing Pumpkins, and Queens of the Stone Age have played a role in the band's revolving lineup under the core songwriting duo of Keenan and Howerdel.
