Junkie XL started as a live-act in 1995 and debuted in 1997 with their album Saturday Teenage Kick.
Even though Junkie XL was technically a group, all tracks were created and produced by Tom Holkenborg (born 8 December 1967 - Lichtenvoorde, The Netherlands). Junkie XL officially became a solo project when Rudeboy left the group after the Big Sounds Of The Drags album.

In 2003 Tom moved from Amsterdam to focus on writing and composing music for video games and films. He's often working together with Oscar-winning composer Hans Zimmer for new movie scores, but also works solo on new material
