Urban review: Lady Sovereign, Jigsaw

In 2006, Wembley's Lady Sovereign, "the UK's fourth-biggest chav", became America's latest rave. Jay-Z deals, Gwen Stefani supports, and an MTV No 1 meant you could hardly fault the 5 ft 1in pop-grime rapper's claim to be "the biggest midget in the game". While the moment has passed – her last single was number 88 here – it's hard not to feel kindly towards anyone describing their new album as "a massive leap forward for mankind". Cure-sampling single So Human proves ingenious, Jigsaw effectively swaps swearing for singing and Britney songwriter Dr Luke earns his keep. Alas, though, the backchat of Let's Be Mates proves as edifying as the top deck of the 43 bus.
