Adam Thomas Jones (born January 15, 1965) is a three time Grammy Award-winning musician and visual artist, best known for his work as guitarist with the band Tool. Jones was rated the 75th Greatest Guitarist of all time by Rolling Stone Magazine and placed 9th in Guitar World’s Top 100 Greatest Heavy metal Guitarists. He is also credited for most of Tool’s music videos.

Jones was born in Park Ridge, Illinois, raised in Libertyville, Illinois, and played violin in elementary school. He was accepted into the Suzuki program, and continued to play violin through his freshman year in high school. He then began to play an acoustic bass for three years in an orchestra.

In addition to playing classical music, Jones played bass guitar in the band Electric Sheep, with Tom Morello of Rage Against the Machine, until Jones moved to California. According to both of them, the band was quite unpopular at the time. Jones never received traditional guitar lessons, but instead learned by ear.

Jones also toured with the Jello Biafra/The Melvins band and contributed to their albums Never Breathe What You Can’t See and Sieg Howdy!. Jones and Melvins Guitarist/Vocalist Buzz Osborne are close friends. Jones also appeared on the Melvins album Hostile Ambient Takeover and the Melvins/Lustmord collaboration Pigs of the Roman Empire.

On Mr. Show, he appeared as the fictional guitarist of Puscifer along with bandmate Keenan, and can also be spotted in the audience seated at a table with Keenan in the series’ first episode.

Jones had a pet Jackson’s Chameleon and a Great Dane named Eon. But according to an interview with Danny Carey, Eon became ill with cancer and passed away. Adam dedicated the song Eon Blue Apocalypse from the band’s 2001 album Lateralus in his memory. Adam’s current Great Dane is called Diablo. He and his wife have a great love for the breed of dogs.

According to his MySpace page, he plays the Xbox 360 video game Halo 3 and owns a rare piece of in-game equipment.

Recently, he has made a number of appearances at the 5th Avenue Manchester nightclub, and is famous for his taste in the music played there.

He will be appearing on the February 2009 edition of Guitar World magazine with Kirk Hammett of Metallica. The two guitarists will be on the front cover.
