I just finished listening through and watching Dave Grohl's 23-minute prog instrumental composition, Play. And it's cool! Very Rush-y at the top, with hints of Radiohead, Opeth and Motorhead throughout. Every bit my happy place.

Ala the first Foo Fighters record, Grohl plays every instrument, recording each part in one continuous take, which is, again, super cool. Suspecting that a really famous dude bashing out progressive rock without his bandmates would earn hilarious scorn from the music intelligentsia, I performed a cursory Google search - holy smokes, are music critics ever dicks and, worse yet, lazy writers. All the more reason to give it a listen. That we could all be Father John Misty.
