German DJ and producer ATB released “9 PM (Till I Come)” in 1998 as his debut single. Built around a distinctive guitar sound created through studio processing, the track became an international dance hit and reached number one on the UK Singles Chart in 1999. Its melodic hook helped define the era’s accessible trance sound. Decades later, the recording remains familiar through dance compilations, radio nostalgia, club sets, short-form edits, and videos that evoke nighttime travel or turn-of-the-millennium electronic music.
