Royal Philharmonic Orchestra / Valery Gergiev

Set to repeat the success of their Tchaikovsky Iolanta last December, Gergiev, the RPO and soloists from the Mariinsky Theatre, St Petersburg present the UK premiere of Rimsky-Korsakov's fairy-tale one-act opera Kashchey the Immortal (in concert performance). Barbican

Us 3

That's 'Us Three' as in 'We Three', not 'United States Three' or 'Oui Three'. One of the better jazz/hip hop acts, not just because of their access to the Blue Note Catalogue for samples, but becasue they're cool and can rap. Astoria

Angelique Kidjo

From Benin, a diva. Never mind the terrible mess they make of the remixes on her new single 'Agolo', feel the vibe live.
