Young Amadeus is growing up in real time with MOZART 250, Classical Opera's ambitious 26-year project following its hero's creative life from childhood to the grave. 2015's start, marking two and a half centuries since the boy wonder's first visit to London, and its sequel had little to show of its main man, but plenty of other, senior composers flourishing in the same years.

You can tell it’s a big deal when even a handful of London critics abandon the capital for a Saturday evening in chilly Glasgow. And there were more besides in the capacity crowd for Birtwistle’s opera The Last Supper, given a semi-staged performance by the BBC Scottish Symphony Orchestra – seemingly anyone who’s anyone in Scottish music, from international composers to conductors and orchestra heads, and way beyond too.

Colin Matthews’s arrangements for orchestra of the 24 Debussy Préludes (originally commissioned by the Hallé) have been widely admired. The BBC Philharmonic’s concert, conducted by Nicholas Collon, at the Bridgewater Hall on Friday night began with three of Ravel’s five piano Miroirs, two of them orchestrated by Matthews (one a world premiere) and one by the late Steven Stucky.

Birmingham audiences are a supportive bunch. There was never much likelihood that they’d greet Andris Nelsons’s first Birmingham appearance since he departed for Boston in 2015 with less than the same warmth that they keep for other former CBSO music directors. Even so, he must have been gratified to walk out to a capacity audience – for a programme of Bruckner and Maxwell Davies – and a 30-second ovation, complete with a couple of cheers, before he’d given so much as a downbeat.

What's not to like, or love, would have to be the sensible response to both the opening programme of Kings Place's year-long Cello Unwrapped festival at Kings Place and its life-enhancing execution.

Revelations in the classical year never stop coming. Even the week before Christmas yielded two performances as good as you're going to get: the sheer effervescence and light-flourishing of Lucy Crowe in ecstatic Bach and Mozart with La Nuova Musica, and Sheku Kanneh-Mason in Haydn's C major Cello Concerto. So any sifting of 2016's musical riches needs to put the truly one-off packages at the top of the list.

Sheku Kanneh-Mason isn't just BBC Young Musician 2016 - he's the year's top player in my books, a master at any level. Despite a contract with Decca, starting with the Shostakovich First Cello Concerto he played in the competition finale, he looks likely to remain loyal to family and friends, including the Fantasia Orchestra, founded this year, in which he's already played as part of the cello section.

Time was when the principal conductor of a top orchestra could afford to refine mastery of a small and familiar repertoire, covering a century and a half of music at most. The rest he (always he) would leave to loyal or youthful lieutenants. The days of such podium dinosaurs are numbered. The likes of Valery Gergiev, Mariss Jansons and Riccardo Muti are outflanked by colleagues, mostly a generation or two younger, who have been trained to view the entire history of Western ensemble music – at least three centuries’ worth – as the right and duty of an orchestra to promote.
