There is an actual documentary about Alfred Brendel on BBC2 tonight, at 11.20pm (not exactly prime-time but we can always set the video if we can work out how to use it). 'Alfred Brendel: Man and Mask' follows the great pianist through two years, during which he works with such artists as Simon Rattle and Matthias Goerne, and explores the influences that shaped his life and musicianship. He's also featured in The Culture Show at 10pm - which has extra culture on it today, including our beloved Felix and his birthday. Here, apparently Brendel reveals a fondness for the films of Bunuel.
I don't know yet whether the documentary will be available on the BBC iPlayer after tonight, but if it is then I will link to it here.
