Sublime Frequencies is an awesome small time house that has a great collection of modern compilations from Asia and North Africa. I discovered them accidentally while perusing the unusually eXperimental section at Ameoba Records. I bought the Cambodian folk music CD.
As a positive review, it's great to see that "world music" is rapdily expanding as the globalizing flood gate on the internet allow audiences not just to hear the megapop stars and the easy listening cross over genres that populate the club and hippy circuit world wide, but on the street real time culture.
The lack of WIPO presence outside of North America and Europe has caused a great explosion of archives of music available from Russian Punk (ПАНК, or пиздец as my homey Vadmin would say) to Thai Top 40.
The imbalance of WIPO is also leading to a strange but familiar situation where Intellectual Property can be "mined" by travelers from less restrictive countries, and the repackaged and commercially sold here. This not only applies to music, but of course everything copyrightable or patentable (the biopiracy arguments have been going on for a while). I generally think most forms of intellectual property are stupid... But how do the ethics of copying play out when the source material was in the public domain to begin with?
