Olov Johansson was first played on NTS on 18 January 2021. Songs played include Polska Efter Erlandsson.

In 1990, Olov became the first world champion of the nyckelharpa (keyed fiddle). He began to play the nyckelharpa in 1980 as a fourteen-year old, and was named a 'riksspelman' (master musician) in 1984. Olov has studied with the legendary Curt Tallroth and Erik Sahlström. He is regarded as one of Sweden's most prominent nyckelharpa players, and is an inspiration for numerous young performers on the instrument. He is teaching regularly at the Eric Sahlström Institutet.

Apart from his association with Väsen, Olov has also played with groups such as Kronos Quartet, the Nyckelharpa Orchestra, as well as solo performances. He has also recorded and toured with the chart-topping Swedish rock group Nordman, and has played on the albums Early Music (with Kronos Quartet) and his solo project, Storsvarten (released on NorthSide).
