Dengue Fever, the Los Angeles-based "Cambodian pop band" I posted about recently, has provided a link on their MySpace site to a website for a documentary about Cambodian pop music. It has a lot of fascinating info about Cambodian pop culture, and includes some great MP3's.
The name of the website is Cambodian Rock. (Duh.)
Here is a track by Ros Serey Sothea:
