Cro Memory Grin is a masterpiece. Thirteen turbocharged tracks indebted to the pleasures and pitfalls of their lives in the modern city of Sydney and to the the first and second waves of international extreme music freaks and loonies: pure fucking aggression. The Oily Boys have graced us with a beast of an album that swells between direct, gripping, tangible hardcore punk and near nauseating psychedelia and throb which at moments feels like either ritual trance or a nervous breakdown. Cro Memory Grin contains near equal measures of tension and release; an exercise in high catharsis.
