Probot

It’s no secret that Dave Grohl possesses the sweetest speed dial this side of Satan, but his Probot project still dropped jaws when it hit. Not only did he enlist a veritable league of underground legends to rock the mic (Tom G. Warrior, Lee Dorrian, Max Cavalera, King Diamond), it turned out that – unshackled from the chains of radio rock – he could forge metal with the best of them. “Centuries of Sin” was the most venomous thing Cronos was involved in since the mid-80s, “Shake Your Blood (featuring Lemmy)” captured that Motorhead magic, and “The Emerald Law” gave Scott “Wino” Weinrich a new obsession. Sure, it’s a self-indulgent side project, but Grohl invites his listeners to dig in.
