Swedish group Hagen was formed in 1996 by Hans Rosen (ba**) and his brother Anders (violin). They quickly added Per Nilsson to the group on guitar and Hans Lundin came in to play keys. Singer Michael Ohlsson also joined up and Patrik Jansson was added to complete the picture. The group released their first album, Corridors of Time, in 2001. ~ Gary Hill, All Music Guide
