This OVA is basically the backstory of Seikima II, which is considered
a legendary band in Japan who sold over 10 million records in Japan alone, it's currently unknown how much they've sold world wide. They were referenced in Fist Of The North Star, Yu Yu Hakusho, etc. They also had a video game and this OVA made based on them and even as far as cereal boxes and other merch. They even did a cover of Deep Purple's "Burn" with Glenn Hughes, was a really great performance. Demon Kakka, the lead singer of the band is a very influential figure in Japan, he has an interview with the late Larry King from the early 90s. His previous name was Demon Kogure. He appeared in quite a few Anime's as a voice actor including Legend Of The Overfiend. One other member of Seikima II, Damien Hamada, has his own band called "Damien Hamada's Creatures" who put out their 1st EPs last year.
This was overall a very enjoyable OVA with some twists and turns.
