When the notorious Bergen-Belsen concentration camp in northern Germany was liberated by the British 11^th Armoured Division on 15 April 1945, the BBC’s reporter Richard Dimbleby was there to record the occasion.

Coming in at around four hours, in two parts, this 2015 documentary is ostensibly about Ol’ Blue Eyes, Frank Sinatra, but really, via the prism of his existence, it’s as much about America’s journey through the first two thirds of the 20^th century.

No orchestra wants its conductor to cancel in the week of a concert.

Bill Brandt’s photographs and Henry Moore’s studies of people sheltering underground during the Blitz (September 1940 to May 1941) offer glimpses of a world that is, thankfully, lost to us. A year and a half after the end of the bombing campaign, the work of the two artists was published side-by-side in the December 1942 edition of the pioneering illustrated magazine, Lilliput.

Waking at a pivotal moment in Black Angel, alcoholic songwriter-pianist Marty Blair (Dan Duryea) momentarily mistakes his new professional partner Catherine Bennett (June Vincent) for his estranged wife Mavis Marlowe (Constance Dowling). Each is a radiant blonde singer, but to Marty they are polar opposites: Catherine the madonna, Mavis the whore.

The 75th anniversary of the liberation of Auschwitz reminds us once again of the unfathomable horror of the Holocaust. The revival of anti-semitism in our own country and elsewhere is why it’s worth telling these terrible stories again and again.

When I reviewed the Philharmonia’s Weimar season last year I expressed a hope to hear more Hindemith performed in London. When, also last year, I reviewed chamber music at Conway Hall I looked forward to my next visit. So a Conway Hall programme including Hindemith’s Clarinet Quartet was like a magnet.

Kurt Weill’s “Broadway opera” – his own preferred description – is an extraordinary and brilliant piece of work. Its music ranges from the seriously dramatic to fun numbers like the "Ice Cream Sextet" and the jitterbug dance song “Moon Faced, Starry Eyed”; there’s a lot of spoken-dialogue-with-music, as well as solos, duets and all manner of ensembles; and the story is both comic and tragic.

"Sadler's Wells! Any more for Peter Grimes, the sadistic fisherman?," a cheery bus conductor is alleged to have called out around the time of this towering masterpiece's premiere in 1945. The side of a "Grimes bus" today would probably proclaim over Britten and the work itself the "brand" of two stalwart perfomers - conductor Edward Gardner and leading protagonist Stuart Skelton, dominant forces of the opera over the last ten years.

Everyone’s doing Weinberg now, or so it seems. The Polish-born composer who became a close friend of Shostakovich was born 100 years ago, and there’s plenty of his music to go round.
