Paul Hartmut Würdig, better known as Sido, is a German rapper. He interprets his artist name as "super-intelligentes Drogenopfer". It used to stand for "Scheiße in dein Ohr", a line from his track "Terroarr".

The Sinti are a subgroup of Romani people. They are found mostly in Germany, France and Italy and Central Europe, numbering some 200,000 people. They were traditionally itinerant, but today only a small percentage of Sinti remain unsettled. In earlier times, they frequently lived on the outskirts of communities.
