Kontjong, Kronchong, Kroncong, Keronchong... as mysterious in spelling as it is in melody. Moody, brooding, beautiful. I have several cassette tapes of similar music that I picked up in Indonesia back in 2000, but digitizing those would require pulling out (and dusting off) a tape player, which seems a little daunting right now. What limited info I have about this style of sound comes from the back of these LP's (and can we just take a nice moment of appreciation for the killer COVER ART here?). Apparently, these melodies:

"Originate from the early Portugese settlers in Indonesia and when the Portugese left and the Dutch settlers came, it was inherited by the Portugese/Dutch Eurasians from grand-grand fathers to grand-grand sons and so on."

Here's another informative link that I dug up about this Indonesian musical evolution.

Other than that, just let the tunes speak for themselves. "Bubuj Bulan" sounds like a ready-made RZA beat. Some serious Mulatu vibes around 1:40. I want more...
