Sully Dominique Sefil, known professionally as Sully Séfil, is a French rapper and record producer whose career began in the early 2000s. His breakthrough came with the 2001 single “J'voulais”, which was certified Gold by the SNEP that same year and reached number 2 on the French singles chart, remaining in the top 50 for 24 weeks, while reaching Number 1 on the Belgian chart for a week. The gold award was presented to him by Richard Branson. Following this success, V2 Records commissioned his debut studio album Sullysefilistic, released in 2001, which remained in the French top 100 for eight weeks. In 2002, Séfil performed at the Urban Peace concert at the Stade de France. He returned in 2011 with the single “On ne vit qu'une fois” and in 2012 with “Street Rock Party”, a fusion of rap and rock recorded for his planned studio album Le French Savoir-faire. Parallel to his music career, Séfil launched the streetwear clothing brand Royal Wear, expanding with lines such as Dumpe Fresh and Rock The Street, with designs worn by artists including Billy Crawford, Matt Pokora, and Pit Baccardi.
