Formed in 2009 by violinist Keisuke Takashima, this is an instrumental band with a progressive rock/metal taste. They have released four albums to date.Although they are an instrumental band, they have released many concept albums and suites, and although they are a guitar-less band with a focus on violins, they have created their own unique world with their one-of-a-kind sound that is inclined towards a metal sound.The music, with it's intricate structure that interweaves fast and slow tempos, has received high praise both from within Japan and overseas.This fifth album, centered around the masterpiece 'THESIS,' which is over 25 minutes long, is a socially conscious album that explores the fragility of human values.What we believe to be justice can instantly be labeled as evil when filtered through a different set of values.What are values? What is justice?The values on which society is based are ambiguous and ambiguous, and we think on an extremely fragile basis.What is right, what is ideal, and what should be shared?Songlist1.
