In 1903, Wassily Kandinsky painted a figure in a blue cloak galloping across a landscape on a white horse. Several years later the name of the painting, The Blue Rider (der Blaue Reiter) was adopted by a group of friends who joined forces to exhibit together and disseminate their ideas in a publication of the same name.

For someone who said when he first took the helm at the Hallé that he “didn’t do much Mahler”, Sir Mark Elder has a pretty good track record. He’s conducted all the symphonies except one over 20 or so years at the Bridgewater Hall, and two of them have been heard under his baton more than once.

Those are no. 9 (it was also recorded, in 2014) and no. 5 – and now, in his final season as music director, he’s begun with the former and will end with the latter, both recalling memorable experiences from the past for those who witnessed them.

Will Erich Korngold, the great cinema composer, ever be recognised as a great composer for the live theatre? Probably not, at least until the prejudices that did for him in his lifetime – the prejudice against film and popular music and the prejudice against Jews – are fully corrected in practice as well as in people’s minds. Korngold, happily, is on the way back, though it has taken a long time. Die tote Stadt should, if justice be done, clinch his return.

Saturday’s concert by the BBC Philharmonic was in large measure about the Mahlers – Gustav and Alma. The former’s First Symphony formed the substantial second part of the programme: Frau Mahler was the inspiration of the piece that opened the evening. New Zealand-born Gemma New returned to Manchester to conduct: we saw her last October on the Hallé rostrum, and the energy and fierce attention she brought then were even more evident this time.

Aldous Harding is one of those artists who has you scrambling for Shazam. You might not know the Kiwi singer, but when you hear her music there’s a sudden urgent need to find a place for it in your life.

The drunkard in spring; the lonely man in autumn; the long goodbye. Mahler’s last song-cycle often seems to embody solitude; a resigned, earthly counterpart to the transcendent rapture of his previous work, the Eighth Symphony, as a superstitious talisman to ward off the finality of a Ninth.

Stylistically, Waxworks (1924) was the apogee of German Expressionist cinema in that it was the last pure distillation of the form, in which visual distortion, chiaroscuro, exaggerated staccato acting, and nightmarish atmosphere collectively evoked the angst-ridden German collective consciousness in the early years of the Weim

A lumbering, barrel-chested hulk with a weirdly Ancient Egyptian wedge of hair, the eponymous clay monster of Paul Wegener and Carl Boese’s The Golem: How He Came Into the World compensates for his limited intelligence with brute strength and a dogged determination to see every task through, whether he’s doing the shopping for his household or supporting a collapsing palace by its beams.

Ole Bull sounds like some legendary gun-slinging hero of the Wild West. A legend he definitely was, and he spent long enough in the US to found a migrant community in Pennsylvania. But the Norwegian virtuoso (1810-1880) made his name not with a rifle but a fiddle. Back in Bergen, his birthplace, Norway’s first global superstar bought an entire island, Lysøen. He commissioned a fantasy mansion there from the architect Conrad von der Lippe.

The BBC Philharmonic have given memorable accounts of Shostakovich’s Symphony No 4 in Manchester before – notably conducted by Günther Herbig in 2010 and by John Storgårds in 2014 – but surely none as harrowingly grim as under Mark Wigglesworth this time.
