Sebastian Hoff a.k.a. Promo was born on the 12th of April 1976, and started mixing soon after ;).
When he was 19 years old, he already had a hit on the compilation album Thunderdome IX — The Revenge Of The Mummy, his alias being Section‑8 (together with The Prophet). A second hit was a remix of the song «Don't Speak» by No Doubt, but he mainly produced this track to bully his brother who played in a rockband. This track, called 'Shut Up' (on Shut Up! / Born Whappie!) was a huge succes, although it was not the style of hardcore he wanted to continue with. Promo started to produce a different style of hardcore techno tracks and created his own: melodic, dark, hard and rough.
Most of the top harcore DJ's didn't play the tracks at hardcore parties at the time of release as they wereconsidered too experimental, but they were certainly loved by the harcore crowd.
His idea was to experiment with hardcore, to mix it again and again until he found something new.
Today Promo has his own label: The Third Movement. He started this label with DJ X‑Ess and Catscan. However, after a dispute the latter two decided to leave The Third Movement in 2004 to start their own label and Promo went on on his own.
