The Swedish-Swiss dance act made up of Mandrax and Seb K, best known for the hit "At Night". By the time they started Shakedown in 1999, Mandrax and Seb K. already had a good idea of each other’s musicality: they’re brothers, blending Swiss and Swedish backgrounds. Stephan Mandrax is no newcomer to electronic music. Initially a fan of new wave and punk (making his 1984 DJ debut in a rock club), house music found him in 1986. Stephan moved to New York in 1992
