There’s a new musical genre called new-grass. It’s like bluegrass but newer. If you haven’t heard it, you’re about to. Let’s begin at the beginning or maybe just a little before.

Zack de la Rocha has always been a spitfire and his counter-cultural, geo-political band Rage Against the Machine certainly seemed to fit his emphatic speak-singing style.

Quick, simple songs never sounded so huge. Together, they rock a dirty, sexy, solid set of slab-thumping, indie-blues on their third full-length release. Best of all, it’s powered by the groove.
