Michael Van Dyne, de originele drummer en medeoprichter van Arsis, is weer terug bij zijn oude band. Hij speelde tussen 2004 en 2006 bij de band, maar nam in 2007 afscheid om zich te wijden aan een medische studie.
"I'm looking forward to working with my friend Jim again, as well as the great people at Nuclear Blast. Judging by the new material that [guitarist/singer] Jim [Malone] and [guitarist] Nick [Cordle] have been working on, I think we may be sitting on some of the most memorable and thrashy Arsis material written to date. Due to obligations with my full-time career, session drummers will most likely be utilized for big tours that Jim wishes to do in the future... However, regional shows and occasional mini-tours or festival gigs either here in North America or overseas are a definite possibility (and something I'd be totally psyched to do) if our collective schedules allow it. Good times."
Nadat Mike Van Dyne bij Arsis vertrok om te studeren, nam de groep het album 'We Are The Nightmare' (2008) op met drummer Darren Cesca. Kort na de release werd Darren ontslagen wegens "muzikale meningsverschillen". Darrens opvolger werd David Kinkade, die onlangs bij Arsis vertrok.
