There is more than one artist under this name: 1. Koro was a hardcore punk band from Knoxville, Tennessee, that existed from 1982 to 1984. The band might have been forgotten if not for a remarkable self-released 8 song 7", recorded in 1983.
The 7" has been bootlegged twice, once in small quantities with a cover similar to the original, and once recently with a different cover and lyrics.
They gained their name from a psychiatric syndrome found mainly in China.
