Further details on Vol. III - including a tracklist and release date - have yet to be announced. Mushroomhead split with singer Waylon Reavis in October over what the vocalist described as "irreconcilable differences with band ownership" after 11 years with the group.

Reavis said: "My time in Mushroomhead had run its course. I have 11 years of wonderful memories, but I'm ready for something else in my life. I'm ready for a change. I've lived the same monotony for too long.
