It’s incredible to think that Zagreb punk-pop phenomenon Hladno Pivo (“Cold Beer”) have been around for thirty years, during which they have earned widespread respect as one of Croatia’s most authentic, unpretentious and down-to-earth groups. They celebrate their longevity with this open-air concert at Gripe Fortress (site of the Croatian Maritime Museum), during which they will play their way through a huge repertoire of songs - most of which the average Croatian music fan knows by heart. Hladno Pivo’s texts, full of social comment, political satire and vulgar humour (U ritmu moje dlakave guze or “In Rhythm With My Hairy Arse” being one of their more memorable song titles), are unlikely to make much of an impact on the non-Croatian outsider. But their melodies are darn catchy, and if you’re not humming them by the end of the evening you just weren’t there.
