Awhile ago I found this blog which posts links to mp3s of psychedelic rock from around the world, including a few lps from Korea, such as Shin Jung-hyun and the Men's 1972 album "Woman of the Evening Sun." Have a look here for the album, or here for their long take on "Lies" from another album. Not an amazing album, but its standout would be the 10 minute version of "Beautiful Rivers and Mountains, " which can be listened to at youtube:
In finding the above video, I realized there's a lot more of Shin's stuff up on Youtube, including one of my favourites, Kim Jung-mi. Here's her singing one Shin's best psychedelic folk songs, "Bom."
You can also find her singing "Baram" and what is likely my favourite version of "Beautiful Rivers and Mountains."
You can also see her performing live here and here. You've gotta love her suit.
