I just chanced across the website of Kim Young Suh, a physicist who has been teaching at the University of Maryland for some time. Kim was born in Korea in the 1930s, under the Japanese colonial government. As part of his website, he was quite a long and fascinating section on the music of Korea and Asia when he was growing up. It’s really fascinating, with hundreds of links to singers and music from Shanghai, Korea, and around the region, from the pop standards of the day to his classical favorites. It also talks a lot about Japanese propaganda songs and life in that period before independence. Just great stuff. You could spend hours listening to all his links.
