Barbara Hannigan, we all know, is game for anything. This Canadian soprano with the pearliest tones and the dramatic instincts of a Sarah Bernhardt can find beauty and meaning in almost every contemporary composer’s barbed wire. Recently she’s been cavorting on stage as Alban Berg’s Lulu; earlier this month, for a sliver of Ligeti, she paraded herself on the Barbican platform as a gum-chewing schoolgirl in a naughty micro-skirt.

To pair Rachmaninov’s brooding and little-performed The Miserly Knight with Wagner's brooding but much-performed Das Rheingold is an audacious piece of programming. The operas share an interest in the mortal power of money, and Rachmaninov’s score has a more distinctly Wagnerian colour than much of his later work. To do so in a single evening, requiring substantial cuts to the score of Rheingold, and to stage them in the Royal Festival Hall, shows boldness verging on the reckless.

Offshoots of the Venezuelan El Sistema’s worldwide dissemination as well as other youth and music projects continued to bloom and grow in 2014. The morning after what was the orchestral concert of the year for many who caught it, Alexandra Coghlan (see below) and myself included, players of the European Union Youth Orchestra reconvened in the Albert Hall to workshop three classics with musicians from nine British youth orchestras and London schools.

In words and music Harrison Birtwistle isn’t always as gruff as he’s been painted. Interviewed over the summer during one of his 80^th birthday Prom concerts, the composer tossed off enough humorous remarks to suggest that a new career could almost beckon as a stand-up comedian touring the northern clubs.

If Brahms’s First Symphony has long been dubbed “Beethoven’s Tenth”, then the 23-year-old Rachmaninov’s First merits the label of “Tchaikovsky’s Seventh” (a genuine candidate for that title, incidentally, turns out to be a poor reconstruction from Tchaikovsky’s sketches by one Bogatryryev).

Music lovers invariably divide into two factions over the Brahms piano concertos: those who thrill to the elemental D minor and those who prefer to bask in the more reflective charms of the sumptuous B flat Second Concerto. I’m a D minor man myself, secretly convinced that the four-movement Second would prove a far more startling piece if it began with the second movement. But then again it depends who plays it and Lars Vogt with Yannick Nézet-Séguin and the London Philharmonic Orchestra seemed to find new dimensions in its extravagant elaborations.

Even the cold breeze along the Thames played its part in conjuring the chilly, epic Finnish landscapes of Jean Sibelius last night, though Finnish maestro Osmo Vänskä and the perfectly weighted phrasing of the London Philharmonic Orchestra can take primary credit. It’s unusual to have a single-composer programme these days, but Vänskä justified his repertoire with a performance of taut, lyrical and evocative power, which connected and illuminated different areas, historical and generic, of Sibelius’ career.

Comparisons, even on paper, between two season openers from London orchestras could hardly have been more instructive. I didn’t attend Valery Gergiev’s London Symphony Orchestra concert last week, for reasons several times outlined on theartsdesk. But quite apart from the fact that Gergiev and his court pianist Denis Matsuev are active supporters of Putin's “Might is Right” campaign in the Ukraine – a situation which tens of thousands of Muscovites are beginning to challenge – Matsuev is also the worst of barnstormers.

The Russian conductor Vladimir Jurowski, chief conductor of the London Philharmonic Orchestra, heads its major new series devoted to the music of Sergei Rachmaninov, in context with his forerunners and successors. This is to be the largest celebration of Rachmaninov ever undertaken in a single season, with 11 concerts to include all the composer’s key works for orchestra, including some in rarely heard early versions, placed in context with music by his inspirations, contemporaries and successors including Wagner, Tchaikovsky, Szymanowski, Scriabin and Vaughan Williams.
