Dave Grohl's new album, Dream Widow: Dream Widow, March Of The Insane
I'm only 3 songs in and that's the one I'm at right now. I'm still checking it out and haven't heard it all yet, but seems like a heavy metal tribute type thing. Lots of energy and old school thrash and metal sensibilities. Something different for Dave, and maybe the rest of the band? I don't even know who all is in this aside from Dave.
