Where did all the terrific programming energy of last year’s The Rest is Noise festival go? One answer – surprising given the orchestra’s former Friday night lite status – is into a two-concert adventure by the BBCCO. World to Come, World Once Known has been devised by Principal Conductor Keith Lockhart to reflect the Janus-headed phenomenon of music just before, during and after the First World War.

The Tchaikovsky de nos jours, is Theodore Gumbril’s dismissal of Skryabin in Aldous Huxley’s Twenties novel Antic Hay. For some reason, Alexander Skryabin has suffered more than most from snap judgements of this kind. He has been the woolly theosophist, the vacuous, over-inflated mystifier, the effete, self-indulgent decorative – everything except the refined, disciplined creative genius. It’s high time these images were consigned to the rubbish dump of history, along with the dull-witted Bach, the mad Beethoven, and for that matter the slushy Tchaikovsky.

Depth, height, breadth, a sense of the new and strange in three brilliantly-programmed works spanning just over a century: all these and a clarity in impassioned execution told us why the BBC Symphony Orchestra was inspired in choosing Finn Sakari Oramo as its principal conductor.

The core pulse of Tudor polyphony is often deliciously slow. It gets down to a mesmeric pace of about 30 beats per minute. The listener just has to succumb to it, and the experience, even in the virtually unheated Cambridge College chapel where The Sixteen began its 2014 Choral Pilgrimage last night, was pure pleasure.

Turning every concert into a party, baroque ensemble L’Arpeggiata are performers in the truest sense. Too often early musicians get away with being shy or downright awkward, visibly uncomfortable when forced to introduce an encore. Not so with these European virtuosi, whose signature improvisations give each member (yes, even the percussionist) the chance to step into a starring role. And don’t get me started on the baroque rap that concluded the group’s most recent London concert…

The newly restored Royal Festival Hall organ was inaugurated in a celebratory atmosphere with this gala launch concert, which also marks the beginning of the Pull Out All the Stops organ festival.

A voyage around Beethoven by Ives and John Adams, and then beyond him by Berlioz, added up to a vintage San Francisco Symphony programme from its music director Michael Tilson Thomas. Forty years on from his first concert with SFS, he’s still youthful in demeanour, still flapping with seagull (or albatross) like flamboyancy. But is there a chill behind the showmanship? I ended up feeling that way despite what should have been the ultimate cataclysm of the Frenchman’s concluding infernal orgy.
