Singles brought André small financial benefits; he gained the opportunity to organize a mini-studio.

In 1994 the project turned into the band adding three new members: Ulrich Pöppelbaum, Woody van Eyden and vocalist Morpha.

Despite this success and growing popularity, two members of the project —Woody van Eyden and Morpha — left in 1998; only André and Ullrich remained in the group.

His first track under this name was "9 PM (Till I Come)", included on the Movin' Melodies album, which topped the UK Singles Chart in 1999.

In 2002 ATB successfully took 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".

ATB's hits "Ecstasy" and "Marrakech", both featuring vocals by Tiff Lacey, were included on the album No Silence (2004).

Many of ATB's recent albums have featured vocals from Roberta Carter Harrison, singer for the Canadian band Wild Strawberries.

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 24 March 2013, ATB announced during A State of Trance 600 Miami at Ultra Music Festival that he planned to release his next album during the second half of 2013.

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.

On 10 February 2017, Andre announced through his Facebook account that his upcoming tenth studio album is set to be titled Next (stylized as neXt) and its release date would be 21 April 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.

In 2021, a remake of "9 PM (Till I Come)" by ATB, German producer Topic and Swedish singer Alexander 'A7S' Tidebrink was released on Positiva Records.
