Kneecap is so confident and single-minded in its telling of the semi-fictionalised origins of its titular west Belfast hip-hop trio, that it may make anyone who’s never heard of them feel like a bit of a loser. It’s a film that not only signals a major musical arrival, but ends up feeling a lot bigger than the conventional (and often confining) boundaries of the “music biopic”. Kneecap is the story of Belfast and of the “ceasefire generation” – the ones who were told that all is well, that they live in “the moment after the moment”, even when their nation’s traumas are still writ into their bones. It’s a story, too, crucially, about language deployed as an act of liberation and defiance.
