The Futureheads + Ayah Marar

Another year of free shows in the heart of King's Cross station kicks off with Sunderland's articulate, hugely talented, harmonising post-punkers who did such a sterling acapella cover of Kelis' 'Acapella' a few years ago that they've decided to make a whole album ('Rant') solely from their vocals (on at 6.30pm). These free sesions run till May 4 and include a whole slew of acts including secret guests so keep checking back.
