So I saw this, it's really good, IMO. Starts off in 1970 and you see how Fleetwood Mac started there. Tons of stuff from great musicians who recorded hit records there.
There's a lot about the difference in recording music on tape, and the digital age, where it's so easy to just go in and "fix" things with a computer. But it's handled pretty well. For example, there's a lot of Trent Reznor, and Grohl talks about how he uses the technology as an instrument and not a crutch.
All in all, it's a good Rock Doc, if you like that kinda thing. Lots of history in that place.
