John Allan Zwetsloot[2] (born 30 January 1974) is a Swedish guitarist who previously played with black/death metal band Dissection.
Mattias Johansson, their rhythm guitarist at the time, was just a session player and wasn't dedicated to the band.
He also brought his knowledge and technique of classical guitar to the table,[citation needed] composing three short solo tracks and interludes for the songs.
His solos compositions for the band include: "Crimson Towers," "Into Infinite Obscurity," and "Feathers Fell."
[3] Though he wasn't a part of Dissection for their second album, Storm of the Light's Bane, he shares writing credits on two of the songs.
