If you’ve had half an eye on BBC Four’s conceptual art week, you’ll have noticed that the old stuff is where it’s at, with Duchamp’s urinal making not one but two appearances, equalled only by Martin Creed, that other well-known, conceptual stalwart (who actually isn’t as old as he looks). The BBC would say that this is because 2016 marks the centenary of Dada, the anarchic, absurdist art movement (if a movement is what it was) that saw artists begin routinely to challenge and ridicule accepted ideas about art – what it is, why it is and what it’s for.

Painted during his first trip to Paris in 1900, Picasso’s Le Moulin de la Galette is an outsider’s view of an exotic and intimidating new world. Men and women are seen as if through some strange distorting lens, their blurred, mask-like faces indistinct but for red-slit mouths and coal-black eyes. We seem to be in the room with them, and yet we are isolated. Even a woman looking out from the edge of the canvas gazes straight past us: if not invisible, we are certainly inconsequential.

Bertrand Russell’s History of the World is a charming little booklet that carries a chilling message: “Since Adam and Eve ate the apple, man has never refrained from any folly of which he is capable.” A line drawing shows Adam and Eve sharing a neatly sliced apple followed by a comic depiction of medieval warfare. Next comes “The End” printed opposite a photo of a mushroom cloud. The juxtaposition of image and text drives home the point; all the polemics in the world couldn’t make a clearer case for nuclear disarmament. 

The Tectonics festival concept began in Iceland, 2012, created by the Israeli conductor Ilan Volkov. Although, loosely speaking, it’s concerned with a modern classical programme, there’s a peculiar aspect to Volkov’s orientation that lends a special quality. Much of his chosen music is devoted to environmental shaping, stasis, ambience, stately processes, repetition, and a general questioning, if not confrontation, of the accepted staging stance, and sometimes volume, of a performance.

Art exhibitions hardly seem comparable with battery farming, and yet just as our insatiable appetite for cheap meat gives rise to some troubling consequences, so too does the demand for definitive exhibitions that require vulnerable works of art to be shipped around the world. And so it really is a cause for celebration that an exhibition exploring Eugène Delacroix’s influence in the 50 years following his death maintains its focus, argues its case and thoroughly immerses us in his work, without actually showing us any of his best known paintings.

Described by Courtney Pine as "the most exciting jazz band to come out of the UK" and hailed in the press as the new young lions, Empirical broke cover in 2007, topping album of the year charts with their self-titled debut and picking up wins at the prestigious EBU/European Jazz Competition and the Peter Whittingham Jazz Award all within a few months.

Originally available on cassette only, Odd Nosdam's Trish has now become the producer and former member of hip-hop pioneers cLOUDDEAD's first release for the Sonic Cathedral label. With six tracks coming in at just under half an hour, it falls into the hinterland between EP and album – a kind of musical novella. This means that there are certain constraints at play here, yet the shortened format is, in reality, a strength.

Any number of puzzling and fantastical stories were told by Alberto Giacometti in the construction of a personal mythology that helped secure his reputation as an archetypal artist of the avant-garde. Less heroic than the oft-quoted accounts of his transformative, visionary experiences, the story of his return to Paris after the Second World War is no less poignant, nor significant for all that. Having stowed his most recent works under the floorboards, Giacometti left his studio in 1941 returning four years later to find it – miraculously – just as he had left it.

This was Henryk Górecki beyond the Third Symphony. His otherwise ubiquitous masterpiece was notable by its absence from yesterday's programme. That was surely a conscious decision, and a wise one, allowing his many other important works to come out from its shadow. Górecki turned out to be an ideal subject for the BBC Symphony Orchestra’s “Total Immersion” treatment. His music gradually evolved throughout his career, from acerbic neoclassicism, to esoteric serialism, and then to austere minimalism.

Composer, pianist, producer… Max Richter (b. 1966) is nothing if not prolific, not to mention unique. His traditional training, which included Edinburgh University, the Royal Academy as well as Florence, under composer Luciano Berio sits alongside a fascination with the otherwordly sounds of German electronica and American minimalism. As well as his solo work, which blends emotional depth and power with a refreshingly direct approach, he has collaborated on operas, ballets, theatre, film and television scores.
