I gave up on Radio 3 after Donald Macleod turned it into a soapbox for reactionary propaganda, using Shostakovich at every opportunity to refight the Cold War. I don't find a medium scripted by MI6 any fun to listen to, and almost entirely stopped listening to the radio years ago.
(As far as I know Donald Macleod hasn't died of sclerotic bigotry yet, and when he does MI6 will just appoint another ventriloquist's dummy in his place).

Fortunately I have an enormous collection of ex-charity-shop CDs. Two composers I've been listening to a lot lately are Monteverdi and Messiaen. And the darkest music of the early Baroque, like Schutz at his most elegiac. The Thirty Years War is what we're living in now.
