If Poison Idea is the Bad Brains of Burning Spirits and Gauze is the Agnostic Front, Death Side is the Warzone. Death Side is legendary. Everything about them. Their line up is a who's who of Burning Spirits legends. There might have been hardcore punk in Japan before Death Side, but it was Burning Spirits by the time they were finished. Vocals by Ishiya (of Forward, Smash Detox), Kenji Mukai (of Judgement, Smash Detox), You (of Forward), and the immortal Chelsea (RIP) (of Paintbox, Poison Arts, The Execute). Death Side is everything I just previously described. Fighting spirit. Guitars out of your wildest dreams. A drummer at war with his kit. Lyrics with aspects of fatalism. Death Side is the father of the modern Burning Spirits scene. Don't believe me? There is an even a family tree showing Death Side's impact to the scene.
This is their two albums, all of their EPs, their split with Chaos UK, and all of their comp appearances. If you don't have this stuff, I can't recommend it enough. This is the stuff that makes you better at this game. If you are a drummer or a guitarist in hardcore, this is the type of stuff you need to be listening to.
