The National Youth Orchestra of Great Britain’s standard of playing is consistently impressive, so much so that it’s easy to forget that the ensemble is effectively reconstituted from scratch each autumn. Last night’s fresh incarnation, deftly conducted by Nicholas Collon, sounded as if they’d been playing together for decades, though without any sense of complacency which that might bring. When you’ve 163 teenagers squeezed onto a stage, the worry is that the details will get lost in a blurry soup of sound. But no; this account of Prokofiev’s Fifth Symphony was immaculate.

The musical future looks bright indeed, at least from my perspective. There are more classical concerts than ever going on across the UK on most days of the year, so who can know with any authority what might have been missed? Yet each of theartsdesk’s classical music writers has a special take on the events of 2015, and part of mine has been the special privilege of following a trail of younger players in out-of-the-way places.

Does classical music still matter? Of course it does – sample any one of these ten discs and discover why. All of them are available as CDs as well as downloads – the classical CD shop may be almost extinct, but the physical product refuses to die.

Relatively recent tweaks to the abundant London concert scene have resulted in top-end events right up to Christmas. We have in part to thank the seasonal festival at St John’s Smith Square, postponing the Orchestra of the Age of Enlightenment’s holidays, putting them together with superb soloists and choirs, and serving up major Handel and Bach. One snag: their Christmas Oratorio when I last went to hear it turned out to be only four cantatas out of the sequence of six.

L'Arpeggiata seem to revel in being L'Anachronista. The baroque-jazz group led by the Graz-born theorbo player Christina Pluhar has been proudly and brazenly flouting the dictates of those who set the rules of Historically Informed Performance (HIP) for all 15 years of their existence.

Is it possible for a carol concert to have a cult following? Ex Cathedra's annual Christmas Music by Candlelight performances in St Paul’s Church have quietly grown into a Birmingham institution. The audience has evolved its own rituals: camping out through the long interval in the box pews, and sharing improvised picnics of mulled wine and mince pies.

Imagine knowing Hamlet as a four-act play, or The Ambassadors without its bottom third. Imagine  Mozart’s Requiem as a torso that halts eight bars into the Lacrymosa, or Mahler’s Tenth as the lone Adagio (as, indeed it too often appears). We might admire them all the more for what we ached to feel whole as their creators intended.

It’s boasting, but surely true, to claim that London offers the biggest number of classy Christmas concerts in the world. How could it be otherwise with established seasonal festivals based around Spitalfields, St John’s Smith Square and the over-restored but still amazing Temple Church whose founder Knights Templar bring Dan Brown fans in droves and an inevitable daily admission fee of a fiver?
