Quantum Catastrophe

Brain Drill’s debut album, 2008’s Apocalyptic Feasting, was the kind of onanistic display of guitar splatter over relentless blast beats that inspires awed laughter. Two years later, they learned how to write songs and were much better for it. Guitarist Dylan Ruskin is still a one-man fretboard fireworks display on Quantum Catastrophe, but bassist Ivan Mungula (real name) makes the most of a few spotlight turns and the tracks have dynamics — tempo changes, choruses, and clean sections that are occasionally quite beautiful.
