ATB (born as André Tanneberger on February 26, 1973 in Freiberg, Saxony, Germany) is a German DJ, musician, and producer of electronic dance music. According to the official world DJ rankings governed by DJ Magazine, ATB is currently (2008 list) ranked #25.

André Tanneberger started his music career at the dance music group Sequential One. He was the brain of the group from 1993 to 2002. In 1998, Tanneberger also started a solo project named ATB. His first track under this name was "9pm (Till I Come)", included in the Movin' Melodies album, which topped the United Kingdom music charts in 1999 and is widely regarded as the UK's first trance number one. The track features a guitar riff that became hugely popular. This guitar sound, which he accidentally found while experimenting with a new producing deck, became the trademark of his early hits. ATB continues to evolve and change with every album. His current style involves more vocals and varied sounds, with frequent pianos.

Despite only releasing a few more singles in the UK, namely "Don't Stop!" (No.3, 300,000 copies sold[citation needed]) and "Killer" (No.4, 200,000 copies sold), he still regularly releases music in his native Germany and in other parts of Europe, where he has scored big hits such as "I Don't Wanna Stop" and his cover of Olive's 1996 hit "You're Not Alone".

Two Worlds (released in 2000) was his second studio album. It is a two-disc album based upon the concept of different types of music for different moods. The titles of the two CDs are: "The World of Movement" and "The Relaxing World". This album includes two songs featuring Heather Nova: "Love Will Find You" and "Feel You Like a River." Also the song "Let U Go" features on the "The World of Movement" disc featuring the vocals of Roberta Carter Harrison from the Canadian pop band Wild Strawberries.
