Last year saw Esperanza Spalding pip Justin Bieber to the post for Best Newcomer Grammy, and play two sell-out concerts at the Barbican with her Chamber Music Society project.

This year, she brings her driving, funk-influenced alter-ego to the fore with latest release Radio Music Society, which plays the Royal Festival Hall hot-on-the-heels of selling out Camden's Koko.

'If Spalding can get rock audiences singing Wayne Shorter tunes, then she really has got a musical Midas touch that goes well beyond the confines of just being jazz's next big thing.' Jazzwise
