This week we’ve a brilliant, budget-priced box of Beethoven symphonies played on authentic instruments. It’ll remind you of how much fun there is to be had with this most iconic of composers. A historical recording of a famous cellist reappears, but the best reason to listen to the disc is to hear a famous Czech conductor achieving miracles. And there’s an entertaining, educative DVD featuring a conductor who’s in his element when addressing an audience.

"Love comes now. You have to start with love," urges Sarah Kahn (Samantha Spiro) early in Chicken Soup With Barley, and it's inconceivable that Dominic Cooke's knockout production of Arnold Wesker's 1958 play could have sprung from any other starting point. There's talk later in Wesker's three acts (taken here with only one interval) of seeing people in the round, which is exactly what the writing, not to mention Cooke's superlative ensemble, manages to do: the political and the personal conjoined in a compassion that one might describe as clear-eyed if only it didn't prompt from an audience such honestly earned tears.

Ghosts legendary and personal dog the nostalgic footsteps of Elgar's utterly characteristic late Piano Quintet - though who knew the old man had as much red blood in him as last night's world-class team managed to squeeze out? And circumstantial ghosts have often niggled during the little portion of the Wigmore Hall's century-and-a-decade history I've witnessed, namely the spectre of sweltering at the back behind rows of nodding heads seemingly as old as the hall itself. But there are also the noble spirits of great performances, and heaven knows this sedate old venue has seen a few of those. I've already heard one such this year, and yesterday provided another.

Cambridge University, cradle of Newton, Keynes and Wittgenstein, of Wordsworth, Turing and Tennyson, has produced 15 prime ministers and more Nobel Prize-winners than most nations. In its 200-year history, the university’s debating society has hosted princes, politicians and leaders in every field: the Dalai Lama, Winston Churchill, Nelson Mandela, and last week a 25-year-old east-London DJ, Kissy Sell Out.

In a world crying out for even below-mediocre ballet choreographers (Benjamin Millepied, anyone?), the Dutch old master Hans Van Manen is an extraordinarily well-kept secret. Why a man of such superb balletic accomplishment, theatrical instincts and calligraphic and technical skill remains barely acknowledged in Britain is presumably down to sex. His idea of sexy ballet, that is, being alien to upright British sensibilities.

It’s Holy Wednesday in Cuenca, and going round the corner into Cathedral Square I’m surrounded by hordes of guys in multicoloured mufti who look like the Ku Klux Klan, with unnecessarily pointy hoods. Twenty of them are carrying a heavy float with a large statue of Jesus on it. In Cuenca things are fairly austere, compared to other places where there’s a lot of self-whipping, or where, if you have sin on your conscience, you may end up banging nails into your hands, as in Mexico. Still there are alternative amusements – the Copa Del Rey final of Real Madrid v Barcelona is blaring out of bars – and it’s the 50th edition of Cuenca’s Religious Music Festival.

Last night Murray Perahia played Bach, Beethoven, Brahms, Schumann and Chopin, and we heard, quite simply, Bach, Beethoven, Brahms, Schumann and Chopin. Nothing more need be said, if one follows the Cordelia principle to love, and be silent.
