We very much like welcoming musicians to Soundtracking, so we were incredibly excited to learn about a documentary on the life of superstar Sri Lankan / British rapper M.I.A. - not least because Edith has been a huge fan since her days at BBC Radio 1.

Matangi/Maya/M.I.A. was directed by her longtime friend Steve Loveridge, and follows 22 years in her life - including her rise to fame and her perspective on the controversies sparked over her music, public appearances and political activism. It has been incredibly well-received, and won a special jury award at this year's Sundance Film Festival.

Obviously, you'll hear plenty of M.I.A.'s work throughout the conversation, and also find out about some her musical and cinematic influences.
