Tanneberger started his music career with the dance music group Sequential One. In February 1993, Sequential One released their debut single "Let Me Hear You", followed by "Dance"/"Raving". Singles brought them small financial benefits; André gained the opportunity to organize a mini-studio. In 1994 the band increased by three members: Ulrich Poppelbaum, Woody van Eyden and vocalist Morpha. In early 1995 the House Nation label released the group's first album, Dance.
After the great success in his native Germany, Sequential One gradually became known in other countries of Europe. The second album, Energy apart from Germany, was also released in the Netherlands, Austria, Switzerland and Hungary. Despite the success and growing popularity, two members of the project—Woody van Eyden and Morpha—still left in 1998. Only André and Ullrich were still left in the group. In 1999 Sequential One ceased to exist. Shortly before the collapse, André managed to release the last single "Angels" and the compilation album Decades.
In 1998, Tanneberger started a solo project named ATB. His first track under this name was "9 PM (Till I Come)", included on the Movin' Melodies album, which topped the United Kingdom music charts in 1999. The track features a guitar riff that became hugely popular. This guitar sound 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!" and "Killer", 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". The song "Let U Go" featured on "The World of Movement" disc featuring the vocals of Roberta Carter Harrison from the Canadian pop band Wild Strawberries. The song "Enigmatic Encounter" features music from the music project Enigma.
His third album, Dedicated, was released in 2002. It includes two top hits: "Hold You" and "You're Not Alone". The title refers to the September 11 attacks. In 2002 ATB successfully took the ATC's record label to court and sued and were forced to change its name to 'A Touch of Class'.
In 2003, ATB released Addicted to Music, which included hits such as "I Don't Wanna Stop" and "Long Way Home". The same year, ATB's first DVD of the same name was released. It featured all his videos, a tour documentary and photographs.
ATB's hits "Ecstasy" and "Marrakech", both featuring vocals by Tiff Lacey, were included on the album No Silence (2004). "Marrakech" was also included on the soundtrack for the film Mindhunters.
In 2005, ATB released Seven Years, a compilation album of 20 songs, including all his singles. Additionally, Seven Years includes six new tracks, including the single "Humanity" with Tiff Lacey and the 2005 rework of "Let U Go". Many of ATB's recent albums have featured vocals from Roberta Carter Harrison, singer for the Canadian band Wild Strawberries. On 7 July 2005 he married his long-time girlfriend Anna.
His next album, Trilogy, was released on 4 May 2007. The single "Justify" was released from The DJ 4 in the Mix compilation. The single "Renegade" was released on 12 April 2007, and features Heather Nova. The third single was "Feel Alive", released in July the same year.
In a Trance.nu interview on 11 May 2007, ATB considered "Don't Stop!" to be his worst production to date, and he no longer stands by it, due to it being similar to his first hit, "9 PM (Till I Come)".
The album Future Memories was released on 5 May 2009. "What About Us" was released as the lead single prior to the album's release. Further hit tracks include the collaborations with Tiff Lacey on "My Everything", "Still Here" and "Missing" (a chillout cover of Everything but the Girl's classic).
On 29 April 2011 Distant Earth was released, followed by Distant Earth Remixed on 16 September 2011.
On 8 June 2012 Sunset Beach DJ Session 2 was released. On 24 March 2013 ATB announced during A State of Trance 600 Miami at Ultra Music Festival that he plans on releasing his next album during the second half of 2013. In September ATB posted that he's working on the last track of the album and that the new album will have 24 songs on 2 CDs. In addition, he announced that he would be bringing the ATB in Concert series to the United States with shows in Los Angeles, San Francisco, Chicago and New York City. Previously ATB had kept the past six ATB in Concert shows in Eastern Europe.
ATB released an album titled Contact on 24 January 2014.
On the February 10, 2017, Andre announced through his Facebook account that his upcoming tenth studio album is set to be titled "Next" (stylized as "neXt") and its released date would be April 21, 2017. The album will be available in three versions: standard double-disc CD, Limited Edition Box and 12" double-vinyl package, which could be pre-ordered through Amazon starting with the day of the announcement.
