V.A.: 오토베스트10 제1집 (해바라기/사랑) [omnibus]
This seems to be a pop/rock compilation with different bands from the 70s.
I recognise a comparable sound to Pearl Sisters (2), Oh Jung Sun with a great track (track 3, but there seems to be 3 tracks on it, so two are less essential), April & May (track 4 is best, and two more or less good tracks from which I thought were by similar dual harmony singers).
Some of the listed songs are more mainstream, but there is use of fuzz guitar more often.
The Oh Jung Sun track, track 3, I think is the most essential one.
The compilation is good enough as an introduction to know what to expect from Korean pop/rock music but it is not really so special.
