Congratulations to Polly Jean Harvey for winning the Mercury Prize for the second time, the only artist to do so. Harvey won for her album Let England Shake, a wonderfully conceived and elegantly controlled tribute to a nation and its armed forces. 10 years after her first win and deeply affected by the aftermath of the World Trade Center attacks in 2001, Harvey has created a deeply involved album that burns slowly but lacks cohesive and direct execution. It dances around delicately, almost lacklustre in its approach and delivery, with hard-hitting graphic lyrics intertwined with softened distanced vocals and music. But in creating a channel for silenced voices and lost lives, you can't argue with the sentiment.
