Marc Wichmann, known professionally as Sleepwalker, is a German rapper, producer, and DJ. His career began with collaborations that included working with DJ Ben Kenobi and MC Mr. Schnabel, contributing to the underground project Style Liga. In 2001, Sleepwalker gained significant media attention through his collaboration with the Hamburg City Allstars on the single "Vorsprechtermin", which charted for nine weeks in Germany, peaking at Number 44. This success was followed by an album of the same name, Sleepwalker bittet zum … Vorsprechtermin, released under Motor Music and selling over 50,000 copies. Sleepwalker's solo discography does not include the albums Flower Of Life, Amenti, or Return to Nature, but his 2001 EP Vorsprechtermin remains a notable release. In addition to his music, Sleepwalker has been involved in film, contributing to the soundtrack of the movie Dicke Hose in 2009 and hosting a monthly internet radio show called "Sleepy’s World of Music" since early 2012. He was also part of the Hip-Hop formation Hamburger Hill from 2002 to 2004 and produced the song and music video for "Satan Klaus" by Swiss in late 2012.
