Grand Magus (formed in 1996) is led by one Janne Christofferson (better known as JB), who also fronts the mighty Spiritual Beggars. While the Beggars are more in the traditional Deep Purple/Mountain camp of early rock/metal, Grand Magus opts for a bluesy, stoner-laced doom vibe, heavy on the early Black Sabbath riffing and tempos, with JB's gruff, forceful vocals blending perfectly with the music. He was nominated 6th best international vocalist in the annual Burrn! Reader’s poll of Japan.

Bass and backing vocals are done by Fox, a founding member of Grand Magus, who is also bassist in Bajen Death Cult.

Seb is the drummer, who joined Grand Magus in April 2006, also drummer in Plankton, ex-Fortune, ex-Four Sticks, ex-Southfork, ex-Glenn Hughes.

Fredrik 'Trisse' Liefvendahl played drums from 1996 to 2006.

The band have released four albums to date: a self-titled effort released in 2001 (re-released in 2005 as an expanded version with three bonus tracks), Monument (2003), Wolf's Return (2005) and Iron Will, released Monday 9th June 2008.
