Guessing games with the Mercury Prize

Anna Calvi, One Breath: Imperious south London singer, whose music walks a tightrope between Nick Cave and 1970s troubadours, such as Tim Buckley. Her full-fat playing draws on cinematic influences, such as Ennio Morricone. Calvi’s second LP doesn’t represent a huge creative leap forward — but is piled high with memorable riffs and choruses. Will She Win? Probably not.
