Sound City Reviews
Great story: this shitty little studio where some of the greatest songs of all-time are recorded. So that's pretty interesting and you get a little behind-the-music stuff with some of those artists.
Where the movie strays is after the studio closes and Dave buys the board. That story is still great, but the final 30 minutes or so are just musicians jamming out in Dave's new studio with the old board. If I knew the songs maybe it would be more interesting, but I'm not much into artists just jamming together. Still, I love my music and there are some good artists in there.
