Shakedown is a Swiss musical project, known internationally for its 2002 hit single, "At Night". By the time they started the group in 1999, Stephan Mandrax and Sebastien Kohler were two brothers who blended their knowledge to form their genre, a modified disco infused house crossed with electro. 　　The 1980s 　　Stephan 'Mandrax' Kohler, a fan of new wave and punk, made his 1984 DJ debut in a rock club. He discovered house music two years later and felt the need to explore the sub-genre of acid house. 　　Early 1990s 　　Stephan moved to New York in 1992, starting the labels, Liquid Groove and Boombastic and with the American DJ, Mike Delgado. 　　Late 1990s 　　In late 1999, Stephan returned to Switzerland to set up a new home and recording studio. After a stint studying and working as a sound engineer in London, from 1993 to 1996, Sebastien also returned to Switzerland and started the Bel-Air Project and the label Cornflex, which lasted from 1997 to 2000. In 1998, he released a series of CDs including the single "Dark Jazzor", one of the earliest recorded songs to include a crossover of drum and bass incorporated with house. 　　Recognising they had developed a complementary set of skills, the two brothers created their musical project, Shakedown. They started working together by producing tracks for other artists, before beginning to record a few demo songs with artists such as Pookie and the vocalist Terra Deva. 　　Early 2000s 　　After a year of recording sessions in New York City and Lausanne, their album, You Think You Know was released at the end of 2001 on Sony BMG. It included the track "At Night".
