Sido, whose real name is Paul Hartmut Würdig, is a German rapper. He translates his name as "super-intelligentes Drogenopfer" in his work (super-intelligent drug victim). It used to stand for "Scheiße in dein Ohr," a line from his song "Terroarr," which means "shit into your ear." Sido sets himself apart by writing violent and provocative lyrics. He always appeared with a silver skull mask on after his 2004 success with his debut album Maske. Since 2005, he has stopped donning the mask, nevertheless. Würdig's career began in 1997 as a member of the duet Royal TS with B-Tight. In the following years, both artists were signed to the Berlin hip hop label Royal Bunker and subsequently, in 2001, to Aggro Berlin. Sido has an agreement with Urban/Universal Music Group as of 2009.
