Former Machine Head members, Phil Demmel and Dave McClain have teamed up with Megadeth’s Dave Ellefson and Bleeding Through’s Brandan Schieppati to drop a new song called “The Permanent Decay.”

Demmel explained that him and McClain originally wrote ideas and riffs for Machine Head but it was ultimately rejected by frontman Robb Flynn. Instead of letting those ideas go to waste, they decided to get to work and drop a new tune.

“Originally when me [McClain] and Phil were in Machine Head, and it came time to start writing stuff for the next record, Phil had some ideas and riffs, and I’m always down there practicing all day. He just came down one day, he had these riffs, we started messing around. I mic’ed up everything in the room on my laptop, and we recorded this stuff live, and then it ended up not being used for anything. Fast forward to all this time later, when we’re both out of Machine Head, and Phil was going out on this guitar clinic tour, and he was like, ‘Let’s record some of the riffs and songs I had.'”

As of now, no one knows if they will continue as a band.

“We don’t know if we’re a band, we don’t know what we’re doing, other than that we all played on this song, and that we dig it. No one knows what the future holds.”
