A Perfect Circle

A Perfect Circle is an American rock supergroup formed in 1999, born from the collaboration of Tool frontman Maynard James Keenan and guitarist Billy Howerdel. Blending brooding, atmospheric textures with heavy alternative rock instrumentation, the band quickly distinguished itself from Keenan's other projects with a more melodic, cinematic sound that still retained an emotional intensity and darkness.

Since their formation, A Perfect Circle has built a devoted following through albums that pair introspective, often politically and socially charged lyrics with lush, layered production. Their live shows are known for immersive visuals and a moody, hypnotic atmosphere that mirrors the introspective nature of their music, making them a staple for fans of alternative and progressive rock.

As a supergroup, A Perfect Circle carries a unique cachet, drawing together musicians with pedigrees from other acclaimed acts, which lends their material a depth and musicianship that has kept them relevant across more than two decades of activity.
