HammerFall
As HammerFall became more famous, some of the band members needed to leave because they were already in other bands. To fill the empty musical spots, Stefan Elmgren assumed the lead guitar and Patrik Räfling assumed the drums and Fredrik decided to remain in the band until a suitable replacement for him was found. In May of 1997, bassist Magnus Rosén joined the band. Stefan Elmgren played some of the guitars on the Glory to the Brave album (such as the acoustic guitars on "I Believe") and Patrik Räfling actually played the drums on all songs in place of Jesper, but only as a guest performers, not members of the band.
