Kenneth Karlsson was born in Åmål, Sweden. He started out playing impro/rock with a few friends in his youth. He went on to develop an interest in classi­cal music, and after a few years he became a student at the Music Academy in Oslo, followed by further studies in the Netherlands. Since then Karlsson has been active as a pianist specializing in the areas of contemporary and classical music, and improvisation. During the 1980s and 90s he was a member of groups such as Ensemble K4, Oslo Sinfonietta and Aquari­us, and has collaborated with mezzo-soprano Hilde Torgersen for more than 20 years. He has also played in various improvisation groups over the years, in­cluding the quartet Point 4 with Jon Balke, Ingar Zach and Bjørn Rabben.
