Angine de Poitrine have gone from KEXP darlings to late-night US television in what feels like the blink of an eye. Proper breakout stuff for a band built on the sort of deliberately awkward, fascinating sound that shouldn't work on screen but somehow does. If their UK telly moment back in June was the moment British audiences cottoned on, then Monday's Fallon appearance might be the point where American viewers suddenly start paying attention. There's something brilliant about watching a band this uncompromising, microtonal, mathematical, getting dressed up for the occasion and get their shot on mainstream television. We're betting this one'll be doing the rounds online before the week's out.
