Sido’s real name is Paul Würdig. He was born on 30 November 1980 in Berlin. The singer created his pseudonym by taking the first letters of the phrase Super-intelligentes Drogenopfer, which means, “super intelligent drug victim”.
The future celebrity lived with his younger sister and mother in Eastern Berlin until he turned eight years old. In 1988, the family moved to western Berlin to a poor neighborhood. Paul was expelled from school for drug use. Wurdig spent his childhood on the streets in a poor neighborhood with immigrants.
In 1997, Sido decided to become an artist. Together with a gangsta rapper B-Tight, the aspiring celebrity recorded several songs. The artists called their duo Royal TS. At one of the local performances, the young men were noticed by the founders of the label, Aggro Berlin. At that moment, they decided to form a label and offered Sido and B-Tight a contract. Rappers agreed.
In 2003, Paul decided to start a solo career. He released two solo songs, "Arschficksong" and "Weihnachtssong". Due to offensive language, both singles had some restrictions but a final decision to restrict them from the radio was never made. The music video for "Arschficksong" got an R rating (FSK 16 in Germany). Nevertheless, many clubs wanted to book Sido for private events.
