Whenever a band held in such high regard as are Karen O’s Yeah Yeah Yeahs return with anything that may be deemed an in any way subversive change of tact, there are always going to be dissenters up in arms exclaiming “Sacrilege!” and so forth. Which makes the title of this, the first thing proper to have been extracted from forthcoming fourth Mosquito (anticipated April 15th on Polydor), that bit more apposite. Nonetheless, there’s little to find fault with as Sacrilege is as though a fizzy recomposition of It’s Blitz! highlight Dull Life – a giddy blur of turbid bass and signature full-throttle Brian Chase rhythms. Both O’s vocals and Nick Zinner’s scintillating fretwork prove symbiotic as ever, with the former flittering between porcelain coo and buzzing screech, and the latter oscillating for once strangely restrainedly between softened top-end twinkles and raging, off-the-wall squalls. And then there’s the gospel choir – the finest committed to MP3 in recent times, and that most memorable since that to have so resplendently embellished Screamadelica. “It’s sacrilege you say?” O quizzes though when it’s she and they that’re the sacred figures of the piece they’re surely free to do precisely as they please, are they not?
