Karlsson grew up in Hässleholm, Skåne (the same town as fellow electronica producers Andreas Tilliander and Stefan Thor (Folie)), but is currently based in Malmö.

Both the album and the single Det snurrar i min skalle are released on Tellé in Norway, the same label as Röyksopp, Annie and Kings Of Convenience.

Some unexpected help came from the file sharing community The Pirate Bay, who on their website encouraged their visitors to vote for him (without Karlsson's knowledge).

In 2015 he produced the ...Baby One More Time-single by the Swedish singer Tove Styrke, a cover of Britney Spears's hit song released in 1998.
