Shin Joong-Hyun & The Donkeys - Mah-eum (Heart) 1969

Unfortunately American / British rock and roll influnence in (bad) Korea did help produce a few bangers inlcuding this fuzz soaked bit of psychadelic pop rock perfection.

Shin Joong-Hyun wasn't exactly a radical, but after the General's coup he was comissioned to write a song about the the glory of General Park Chung Hee. Instead he wrote a tune about the glory of Korea's natural beauty. He was arrested and had all his equipment confiscated.

Later he was impisoned again for selling weed, tortured, and sent to a 'psychiactic facility' where he remained imprisoned for years and banned for performing in (bad) Korea.

Unfortunately I've never known much apart from some other credits from liner notes about Lee Jung Hwa, who provides the song-making vocal.
