Last month, MACHINE HEAD completed its final tour with guitarist Phil Demmel and drummer Dave McClain. Demmel, who first played with Flynn in VIO-LENCE in the late 1980s and early 1990s, said in a statement saying that it was “simply time” for him “to step away and do something else musically.”

In a video message, Flynn blamed Demmel and McClain‘s departures on the fact that he and his bandmates “have grown apart as people. Musically, we’ve grown apart. I have held on too tight to the reins of this band, and I have suffocated those guys.” He went on to say that his “rough edges” have given MACHINE HEAD the success that it has, but “they’ve also hurt the people around me. I’ve got a lot of drive, but I’ve got a lot of anger and rage. And that drive of mine has alienated folks in the band,” he said.

MACHINE HEAD‘s latest album, “Catharsis”, was made available in January via Nuclear Blast.
