That's the scene I'm talking about, it's after Sound City closes and he brings it home with him. I haven't watched it since it was released, but isn't he jamming with Josh Homme or something?
Yeah josh Homme and Paul McCartney. Will give the album they came up with a listen later. At least they supported what Trent Reznor is doing the man is a genius.
Its well done and portraits a piece of rock history. You need to sit through a lot of "digital bad, analogue good" bs, but as a fan of almost every person in the movie I enjoyed it.
Decided to watch it too. Pretty interesting casual entertainment if you're into the music, as you say. Muscle Shoals is good too. It's basically the same documentary - just another recording studio.
