Straight out of south London and determinedly DIY, Goat Girl are feisty, furious and fearless. Their incendiary rock, with shades of mid-noughties Cat Power and Medway garage girls Thee Headcoatees, challenges everything from national apathy in Scum to the perils of public transport on Creep on the Train. The latter features the refrain “I really want to smash your head in,” and while singer and guitarist Lottie’s vocals are delivered deadpan, the firestorm of sharp riffs, pounding rhythms and defiant bass make the anger palpable.

Named in honour of Bill Hicks’ alter ego Goat Boy, the all-female four-piece were born when Lottie, bassist Naima and guitarist Ellie met drummer Rosy at this venue in 2015. Having released two singles, they’ve become a tight, vital thrill.

A Slits-like simplicity and repetition distinguish their lyrics in Don’t Care and hit-in-waiting The Man, but Goat Girl’s strong pop melodies go off on unlikely tangents and betray an adventurous, shrewd spirit. Instrumental opener Circus is sinister yet cosy, while No Heart toys with a dark, playground-rhyme melody, bursting into a double-time rhythm before its abrupt end. Naima and Ellie sway hard, Lottie moves against her guitar as if in a seductive dance, and the sold out audience gleefully mosh.

With a debut album due this year, Goat Girl are an aloof, raw proposition – ready to turn indie music on its head and rip its guts out.
