Forget Lady Gaga – Mica Levi, aka Micachu, is modern pop’s true maverick. More likely to sport jeans and T-shirt than frock of flesh, she’s a skinny, scruffy tomboy who can hold her own in a game of keepie-uppie. Her take on music is similarly unassuming, but it’s also, genuinely, extraordinary. Debut album Jewellery, originally recorded for Matthew Herbert’s Accidental label but then snapped up by Rough Trade, deserved to be classed as pop, in her own eyes, because it comprised “short songs, with choruses and verses”. But its wonky and defiantly lo-fi tunes, hammered out on a tiny, charity-shop acoustic guitar, were never going to bother the charts.
