André Tanneberger, under his stage name of ATB, (born 26 February 1973 in Freiberg, Saxony, East Germany) is a German DJ, musician, and producer of electronic dance music. He is best known for his 1999 single “9 PM (Till I Come)” which was a number one single in the United Kingdom.

In 1998, after having been in a band for several years, 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. He has been active since then.
