Band vs Brand

I get documentaries don't have big budgets and sometimes film makers have to sacrifice some things so take this with a grain of salt. This is a decent documentary but it's hard to watch. The quality is ok, but the audio is poor most of time because it seem like they're were just using the camera mic, and that camera was an iPhone. Also, the background music, when it's used, is awful. Again, music rights are expensive, I get that, but if you're making a documentary that revolves around music, use something decent or nothing at all.
