xxxxxxxxxx is excellent, obviously. aaaaa is absolutely wonderful experimental hardcore, like some anarchic pumping perpetual motion machine. Like it will never give up. But, it does eventually to make room for bbbbbbbbb, which is as belligerant as the previous track in its unabashed bashing, only over a bigger timespan. However, to be fair bbbbbbbbb does attempt to diversify its big sound somewhat, retaining its harshness. Which leaves dddd with its deadly serious derangement, continued through the whole EP. There is little that is 'grey' about it. Straight to the point and it's a hard one to take on board, but a creative expression worthy enough to exist. It does exactly what it says on the label. That would be otherwise like asking me to write a critique without being critical, would it not?)
