Grunge has been called Garage Rock's take on Metal. While that may be a little simplistic it does illustrate the relationship between Grunge and Metal.
So it shouldn't be a surprise that former Nirvana drummer and Foo Fighters' virtuoso David Grohl made a Metal album. Like the debut Foo Fighters CD this was initially a one man show with Grohl laying down some mean and heavy Metal tracks.
Then, too top it off, he brought in a veritable who's who of underground Metal (circa '83 to '90) to finish it off. Void's Bubba Dupree, Sepultura's Max Cavalera, Cathedral/Napalm Death's Lee Dorrian and Motorhead's Lemmy make contributions. Even a ringer showed up, Soundgarden's Kim Thayill.
Grohl's take on the project was from a fan's perspective. "I'm just having the time of my life in fantasy camp being able to create something with these people I listened to for years when I was young."
David Grohl is certainly no Metal dilettante. That would be an easy assumption based on Grohl's Foo Fighters who regularly work the pop side of Hard Rock. However, one listen to the tracks he laid down for "Probot" and it's evident that Grohl is not only a major enthusiast but he knows exactly what he's doing. The term "unrelenting" fits. The drumming is intense and the propulsive guitars deliver devastatingly sharp riffs.
Some of '80s best-known or edgiest Metal vocalists (Max Cavalera, Mike Dean, Lee Dorrian, Snake and King Diamond, among others) roar over Grohl's tracks with lyrics of death and destruction. And though Lemmy, on occasion, disputes whether Motorhead is a Metal band, his vocal performance on "Shake Your Blood" is the album's best. The remaining tracks aren't far behind. This is a Metal fan's dream come true.
