Uncommon Nasa presents his first instrumental created from the themes and music of the greatest anime series of all time, Demon Slayer.  Brain Matter is based around the demon Akaza.  Specifically inspired by the aftermath of his epic fight with Rengoku where he threatens Tanjiro before departing the scene with the words "the next time we meet I'm going to spray your brain matter everywhere!".
