Okay, I am a huge fan of the Sublime Frequencies label run by members of The Sun City Girls. Over the last decade the label has released what they call "obscure sights and sounds from modern and traditional urban and rural frontiers." This includes folk and pop from Southeast Asia and the Middle East as well as field recordings, radio broadcasts, and ceremonial music from all over the globe. The label's releases are produced in limited quantities (usually 1,000 copies), and are generally not reprinted.
My all-time favorite Sublime Frequencies release would be Cambodian Cassette Archives: Khmer Folk & Pop music Vol. 1. Every song is a charmer, a hook-laden wonderland of primitive pop goodness.
Mark Gergis rescued over 150 Cambodian cassette tapes from the Oakland Public Library's Asian branch. He set about the daunting task of listening, archiving, and culling the best tracks for inclusion in this great compilation. Most of these tracks are from the post Pol Pot genocide, however there are a few numbers recorded before the Khmer Rouge's bloody rise to power. Knowing that some of these performers (like Sim Sisamouth and Meas Samon) probably ended up as skulls in Cambodia's killing fields adds an air of creepiness and sadness to these otherwise playful recordings.
