Carlos Acosta, Basquiat and Sparks

Nikki Bedi is joined in the studio by writer and broadcaster Ekow Eshun, as well as Professor Sarah Churchwell from the University of London, to cast a critical eye on the week's arts offerings. Plus 'Street Artist' Bambi takes us on an out-of-hours tour of the new Jean-Michel Basquiat exhibition, while John Wilson meets up with Carlos Acosta and dancers from his new Cuban academy. And arch-popsters Sparks perform live in the studio.
