Like Scroobius Pip, Kate Nash’s none-more-London vocals are open to ridicule, but she has so far proved to be quite the charmer. What is most astonishing is how well her songs (previously lo-fi in the extreme) have translated into big, bold pop tunes. ‘Mouthwash’ is easily the equal of ‘Foundations’, its joyful melody helping obscure the limited subject matter. The speed with which she has been thrust into the glare of the public eye might be a concern, but let’s hope Nash can cope with it all.
