ATB's catchy, vocal-driven singles crossed over from clubs to mainstream pop radio, making him one of the most recognizable artists of trance's late-'90s/early-2000s commercial peak. He is best known for his first single, "9 PM (Till I Come)," a euphoric yet chilled-out progressive house instrumental featuring a smooth, distinctive guitar riff. This guitar sound became ATB's trademark, but his lengthy discography has incorporated elements of ambient, drum'n'bass, and rock. His popularity has continued, earning him rankings in numerous international DJ polls, and he has a particularly strong following in Poland, where several of his studio albums and mix CDs have gone gold or platinum.

Tanneberger started his career in the early '90s, forming Euro-house group Sequential One in 1993. The group was moderately successful in Europe, releasing three albums and over a dozen singles until their dissolution in 1999. In the wake of remixes for acts including the Outhere Brothers, Technotronic, and Haddaway, Tanneberger began using the name ATB for his original solo material. He scored a major hit with 1998's "9 PM (Till I Come)," which hit number one in the U.K. and went gold or platinum in a few other countries. Similar-sounding 1999 follow-up "Don't Stop" nearly duplicated the success, and full-length debut Movin' Melodies arrived later that same year. The album also featured the single "Killer," a remake of the Seal and Adamski hit, with Drew Williams on vocals. The song was another smash hit, and began ATB's successful run of vocal trance anthems.

At the end of October 2000, Tanneberger released his sophomore album, Two Worlds. For the album, ATB collaborated with Heather Nova, Enigma, and the Canadian rock band Wild Strawberries. The release was a double CD, the first consisting of more dancefloor-friendly tunes and the second featuring more downtempo/ambient tracks. Following a few more hit singles, third album Dedicated appeared in 2002, featuring a hit cover of Olive's "You're Not Alone." Fourth album Addicted to Music arrived in 2003, along with a DVD of the same name that collected his music videos to date along with a U.S. tour documentary, interviews, and other content. Toward the end of the year, he also released The DJ in the Mix, his first of many continuous mix CDs.

Fifth studio album No Silence was released in 2004, featuring another DVD in its bonus edition. The year 2005 brought ATB's first retrospective compilation, Seven Years: 1998-2005, which featured all of his hits from that period as well as six new songs. The 2007 album Trilogy contained two discs, the first being more pop/rock-leaning and the second more ambient. Future Memories followed in 2009, and also featured separate uptempo/downtempo discs, but this time the uptempo disc featured tracks with higher BPMs influenced by drum'n'bass. The 2011 release Distant Earth expanded the format, not only featuring pop-trance songs on the first disc and downtempo/ambient tracks (including an Armin van Buuren collaboration) on the second, but also a club-centric third disc with the album's bonus edition. The album was followed later in the year by the two-CD remix collection Distant Earth Remixed. Contact, ATB's ninth studio album, continued his tradition of two discs focusing on dance and chillout tracks, as well as a bonus version featuring a third disc of remixes. ~ Jason Ankeny
