Contemporary music from Mali hovers delicately (and creatively) between purist tradition and more or less successful attempts at making things more attractive to a younger and worldwide audience.

If Georg Friedrich Haas’s in vain was a work of political protest when it premiered in 2000, in 2017 it’s a piece that reads more like a commentary – a disturbing musical documentary that captures nearly 20 years of escalating European tensions, suspicions and right-wing extremism. As harmonic consensus gave way last night to chattering confusion, musical certainty to a distorted multiplicity of possibilities, abstraction has rarely felt more pointed, more horribly specific.

John Adams, greatest communicator among living front-rank composers, zoomed into the follow-spot for the second and third concerts of the New York Philharmonic's Barbican mini-residency.

In American mythology, the frontier offered a clean slate, the opportunity to escape from the shadow of the past and live heroically. But, as with everything else in the context of the American Dream, which continues to unfold in real life as if it were but a simulacrum of myth, the present is haunted by the shadow of evil: greed, violence – between white men, but also against native Americans – and personal tragedy. We are prisoners of our past, and nothing can save us.

Gather round the fire, friends: no Santa down the chimney this Christmas Eve, but the curiously comforting Alan Bennett, with his sardonic and occasionally optimistic diaries. The latest published instalment has the slightly wry title Keeping On Keeping On; Bennett tells us the original title was to be Banging On Banging On.

August 1914, September 2001, all of 2016: these are the dates Hungary's late, great writer Péter Esterházy served up for the non-linear narrative of his friend Péter Eötvös's Halleluja - Oratorium Balbulum. Its Hungarian premiere in one of the world's best concert halls, part of the astounding Müpa complex on the Danube in Budapest, was bound to challenge Prime Minister Viktor Orbán's anti-immigrant policy with the libretto's talk of borders and fences, and fear of the other.

Is there anything on a concert programme more guaranteed to make the heart lift – or to prove that a conductor has their musical priorities straight – than a Haydn symphony? If you're tired of Haydn, you're tired of life: there’s no music more joyous, more inventive or more resistant to vanity. Mirga Gražinytė-Tyla chose his Symphony No 6 of 1761, called Le Matin for its opening sunrise and the freshness of its ideas, and it was a delight.

If you thought that a contemporary drama about forcible repatriation, set in an Immigration removal centre, would be about the plight of those confined in places like the infamous Yarl’s Wood, in Removal Men writers MJ Harding and Jay Miller give us something unexpected.

New York-born actor Robert Vaughn, who has died at the age of 83, achieved massive popular success when he starred as the sleek secret agent Napoleon Solo in The Man from U.N.C.L.E., which ran for four seasons from 1964 to 1968 and exploited the then-new James Bond mania to ratings-busting effect. Prior to that, Vaughn, both of whose parents were actors, had racked up a long string of minor credits in American TV and movies, the most prestigious of which was an appearance in John Sturges's 1960 cowboy classic, The Magnificent Seven.

Writing for two pianos is something that – until last year – I had not attempted. I was contacted by Katya Apekisheva and Charles Owen, two pianists who have performed as a duo for many years, asking me to compose a duet for them to perform at the inaugural London Piano Festival. I met Charles back in 2014 when he performed my pieces A Hudson Cycle and Fast Stuff in New York. Time constraints led me to restructure and rewrite an existing piece in my portfolio, Fast Cycles, which I wrote for the late John Scott.
