Sasse is the stage name used by Finnish electronic music producer Klas Lindblad. Based out of Berlin, Germany since 1999, Lindblad has also recorded under the monikers Freestyle Man, Cocamoto Exclusivo, Morris Brown, Sassomatic, Thirsty Monk and Winston Fletcher. He was also a member of electronic act Mr. Negative. Sasse's base-genre falls into the IDM category but also incorporates the styles of house music, electro, techno, Giorgio Moroder-influenced disco and Italo disco.

After several singles released as a remixer (many on his own Moodmusic record label), Sasse released his debut full-length album Made Within the Upper Stairs of Heaven in May 2006. He has also contributed writing and production work to Tracey Thorn's 2007 album Out of the Woods.
