Leann rhymes with what? Sorry – this country crossover star means serious business. She's sold almost 40 million records worldwide, crossing over like many other US megastars from the country chart to mainstream pop success. Her new album 'Spitfire' – featuring Alison Krauss and Jeff Beck – is out in the UK two months before its American release, and she's favouring us further with a big September tour. Come down and check out her powerful pop and punchy vocals.
