A fellow blogger named Peter wrote in to let me know about his blog dedicated to Thai music, มนต์รักเพลงไทย (or MONRAKPLENGTHAI, as it's styled on the header).
This is a great little blog. Each entry features an album of Thai music, with a tracklist, sample song, and a brief explanation/review.
As it happens, the latest post is about Sangthong Sisai (สังข์ทอง สีใส). Sangthong, who died in the early 80s, has been a subject of interest on the blog Die, Danger, Die, Die Kill! (in which author Todd punishes himself for what must be all the bad karma he's built up by watching the worst of Asian cinema, and often without subtitles. See exhibits A through L).
This music blog is now in its fifth month, and has about 25 album reviews so far. Definitely worth following.
