A new genre of music that is the next step in the neo-grunge movement. Imagine Nirvana or Alice In Chains played twice or three times as fast. Then throw in a double kick bassdrum, an unnecessary amount of guitar distortion and pile-driving bass and you get.....grungecore
Guy1: "Dude that new band is absolutely nuts!"
Guy2: "Really? Never heard of em. What kind of music are they?"
Guy2: "Then it has to be good!"
