Get the a perfect circle mug.
A band that started out as a side project of tool that turned out to become a little bit better. Not a lot but enough for anyone to notice the difference. Problbly my favorite band with korn in a close second.

A band whose beautiful lyrics, slow undertones, and rythmic melodies come to play. James Maynard Keenan as frontman, also known from the ever so popular band Tool. A Perfect Circle started off as a lowly side project of Maynards and soon became a huge a hit. Their albums include Mer de Noms, The Thirteenth Step, and eMOTIVE, and also have a few dvd's and box set albums.

After Tool went on hiatus in the late 90's, Maynard made headway with A Perfect Circle and recorded the album for nearly two years before it's debut release of Mer de Noms, with hits such as Judith, Orestes, Magdalena, and 3 Libras. The band it's self was quickly recognized and made it to the big time within little less than a year of it's release, soon after The Thirteenth Step was released. The Thirteenth Step picked up where Mer de Noms and left off, and also made it into the charts, with hits such as Weak and Powerless, The Noose, and Pet. A year or so later eMOTIVE was released, all songs were covers, even one of their own, though it wasn't what most A Perfect Circle fans had expected, it did reasonably well.

A Perfect Circle is on hiatus until Tool decides they want another hiatus.
