That sounds pretty awesome. Another niche one I watched on Netflix was about Creation records, a cult indy records label in England in the 80s. Launched Jesus & Mary Chain and Oasis among many others (including the criminally ignored House of Love). Can't remember the name, though...
Here's one: Check It. Louis CK saw it at a festival and loved it so much he bought it, and you can too, for $5. I thoroughly recommend it. Two thumbs up!
