之前真的是误解了

Cambodian Rocks is the name of a compilation album that this song is on.
Some American guys went to Cambodia in the late 1990s, found a bunch of cool old rock songs on cassette tapes and made that album.


基于以上来源于youtube的资料，可以说，所谓柬埔寨六十年代迷幻摇滚，其实只是一个误会。
并不是人声+乐队的模式录制的唱片，而是西方摇滚青年的无心插柳的fusion杰作吧。
不过，所谓“高棉摇滚”什么的，很带感是没错了。
