Mutoid Man is currently in the studio working on a new album, and with a mystery bassist replacing now-ex-bassist Nicholas Cageao. While Mutoid Man has been keeping who they've been working with under wraps, their label Sargent House may have given it away.
In a photo posted to Sargent House's Instagram stories, it appears as though High On Fire bassist Jeff Matz is in the background playing his signature Dunable Guitars bass. Purveyor of the rumor The PRP also points out that both Mutoid Man's Stephen Brodsky and Ben Koller follow Matz on social media.
See below for a photo of what appears to be Matz, and a photo of Matz's signature bass. As of right now, Mutoid Man is currently vocalist and guitarist Stephen Brodsky (Cave In, Old Man Gloom) and drummer Ben Koller (Killer Be Killed, Converge).
