Su19b have been around since 1997 so expect a legendary Japanese gridncore played the hardcore way. This is not noise noise noise, this is fast hardcore broken by sludgy bits that makes you feel you are listening to a 80s style NYHC, but only more grindy. It’s a 1997 demo cassette released on a 7”EP, so you might think the quality sucks. It doesn’t. Su19b are very active, so if you have any chance to see them live, do it and you will not regret.
