The enormous success of his 'White Ladder' album in 1998 meant that throaty, head-wobbling singer-songwriter Gray was the man to blame for the early-noughties 'new acoustic movement'. That's all water under the bridge now, though – 16 years on from 'Babylon', he's here performing from his hefty back catalogue and new album 'Mutineers' at the iTunes Festival. Support comes from Irish singer-songwriter and Mercury Prize-nominee Lisa Hannigan. Though she's perhaps best known for her work with Damien Rice, Hannigan's own strand of hand-knitted folk has won her a lot of fans, and she'll no doubt get a great reception at tonight's show.
