Wahlgren debuted in 1988 with the single "Funky Raggamuffin/Let the Music Play", a mixture of dancehall and hip hop. He then joined the Stonefunkers and became the group's rapper. This was followed by a few years of cooperation with Rob'n'Raz. Wahlgren then went solo, and had his breakthrough in 1990 with the album "Lettin' Off Steam", which was predominantly hip hop and dancehall. His next album, "One Step Ahead", had elements of soul and reggae, mixing song and rap. His 1994 release, "Original Master", produced by Denniz Pop at Cheiron Studio, incorporated Euro disco into his music.
