This is a song from Guilty Gear, a Japanese video game series heavily inspired by Western rock and metal music. Those influences are easy to hear in soundtracks from across the series. What makes this song in particular stand out is its fusion of progressive rock and heavy metal with elements of traditional Japanese music: the lead guitar tone resembles the sound of a shamisen, the use of abrupt pauses and harsh vocalizations is reminiscent of Kabuki theater, and the background chanting vocals are reciting the words to an actual Buddhist purification ritual called the “Mantra of Light”. I believe this song, along with the game it comes from, is an illustrative example of how Japan has, in the decades since the end of US occupation, taken the Western cultural practices forced upon it and adapted them into a new, uniquely Japanese culture.
