Yeah
I think any genre of music can be done amazingly well except for silence which is of equal value by all performers except John Cage. Silence is also the only genre you get better at as time goes on after your death. Unless you're completely anihilated by a hydrogen bomb. I guess it also depends on when a corpse stops being you.
I like grindcore and was wondering something quite the opposite: Is it possible to make bad grindcore? Like if it were bad I would claim it wasn't really grindcore.
