Volle began as a DJ in the 1980s, started producing remixed records and later original releases, producing Dr Alban's single "Hello Afrika" in 1990. With Tom Talomaa he started the Cheiron Studios on Kungsholmen in Stockholm in 1991, and the next year recruited Max Martin (Martin Sandberg) to the studio. In the following years he produced and wrote songs for several successful Swedish and foreign artists, including Ace of Base, Backstreet Boys, Britney Spears, E-Type, Robyn and 5ive.
In 1998, Dag died of stomach cancer at the age of 35, leaving behind his girlfriend and 11 year old son. The video to The Backstreet Boys' "Show Me The Meaning Of Being Lonely" was dedicated to him. E-Type's album Last Man Standing commemorates Dag with a dirge, the final track PoP Preludium.
