Little do we know about Mark Arrington. One thing is for sure: he played drums on tracks 1, 4, 6, and 8 of Nevermore's debut album. The rest of the tracks were played by Van Williams, who turned out to become Nevermore's steady drummer.
Mark Arrington also played drums on Nevermore guitarist Jeff Loomis' debut, all-instrumental solo album 'Zero Order Phase', released in September 2008.
