Bellaphon were a symphonic/instrumental progressive rock group from the 1980s. They formed in 1981 and released their first full length in 1987, entitled "Firefly". It is regarded as being one of the highlights of Japanese progressive rock even in their own country. After that, they released a 6 song CD called "Delphi", which included unreleased tracks. Even today, they are some of the best prog to come out of Japan.
