This popped up in my Amazon feed yesterday. I'd heard great things about it so I checked it out. I'm a Dave Grohl fan and I can nerd out to recording processes, so it was a no-brainer.
It's a two hour doc about a famed recording studio in Cali called Sound City. Truthfully, I didn't know about all the records it was responsible for other than Smells Like Teen Spirit (which sounds incredible). Turns out Sound City was a dump, but it had a fabled Neve mixing board and a live room that had magical acoustic properties. I won't really spoil the details, but it's neat stuff.
Dave does a good job telling the story of the owners, employees, and artists. The audio mix is great (of course) and overall it's just really down-to-earth and captivating.
If you like music you'll like this film. Plain and simple.
