Screaming Masterpiece is an awesome documentary about the current music scene in Iceland. There's no need to have a history about it because almost all of the artists use their roots and ancestry as their main influences. For such a small island country Iceland has hundreds of different bands that make many different genres of music that all still relate to each other. This is one of the most interesting and entertaining documentrys I have ever seen. It is WORTH seeing. 

 If you happen to already be interested in some Icelandic artist(s) and/or are interested in the culture of Iceland itself, then this short documentary is a decent acquisition for $15. I wished it were more in depth (and thus longer); I mean, they run through about 25 artists rather quickly, but it's a nice, compact sneak-peak at everything if that's all you're looking for. Not bad, but not too great either.
