With his specially tuned guitar (A-D-A-D-A-D), Roger has developed a distinctive sound of his own. In addition to the guitar, he plays the Swedish bouzoki and octave mandolin.

Roger received his first guitar when he was thirteen. Since then, he has studied at Sjövik Folkhögskola and Örebro. He has about 50 followers throughout the world using his tuning, a number still growing. He has given numerous seminars around Europe and the US. Roger has performed together with Nordman, Annbjørg Lien, and the Gunnel Mauritzson Group, among other artists, and has also participated in several stage and theater productions.

Roger's discography includes Nordman (with Nordman), Felefeber, Prisme, Baba Yaga, and Aliens Alive (with Annbjørg Lien), Siluette and Raisu Äut (with the Gunnel Mauritzson Group), The Horse and the Crane by Ale Möller (on NorthSide) and Kat Kombat (Kombat). He also produced the self-titled début album of the group Draupner (on Caprice).
