The first time I interviewed Richard Tognetti he told me a story. Prior to touring the Australian Chamber Orchestra to Japan, the group’s leader and artistic director was discussing publicity with a local PR. Faced with disappointing ticket sales he asked for advice. The response? Remove two letters from the orchestra’s name and transform it into the Austrian Chamber Orchestra – problem solved. It was a tale told with a smile and a roll of the eyes, but one that still had a frisson of Old World/New World truth about it.

Daniil Trifonov, 23, has shot to prominence as one of the hottest pianistic properties of the moment. With multiple competition wins behind him, including the Tchaikovsky in his native Russia, plus a recording contract with DG and a frenetic globe-trotting schedule, he is now a very busy young man. Last night’s London appearance was his recital debut at the Royal Festival Hall, a venue only accorded to the biggest names in the Southbank Centre’s International Piano Series, the new season of which he was opening.

Hector Berlioz knew from early on in life which aspects of death he would want to avoid. He had seen quite enough of the medical textbooks that his father had tried to foist upon him. He had even got as far as smelling the dissecting table as a medical student in Paris, desperately counting the days before he could make his escape into music.

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.

The next revolution of civil disobedience is unlikely to be a ticketed event, with a sedentary congregation of grey-haired, nostalgic former hippies. And the Royal Festival Hall (even at full capacity) is a mere campfire compared to Joan Baez's public of 30,000 protesters of Washington DC in 1967. But politics, where the drum stick is eschewed for the brush, were still the unspoken substance of her first London performance of four.

It was Jim Jarmusch’s film Broken Flowers that first really got Mulatu Astatke major Western attention – in same way that Angelo Badalementi’s music for Twin Peaks gave a rich and strange dimension to David Lynch’s TV epic, there was an even greater sense of wonderful disorientation, or as Brian Eno put it “jazz from another planet,” with Astatke’s music.

The voice no longer soars with easeful power, nor does it possess that tingling, honey-coated purity that gave hits such as “Bridge Over Troubled Water” such emotional force. This should hardly come as a surprise, since Art Garfunkel is now 72. Away from Paul Simon, from whom he split in 1970, Garfunkel has had a long, stop-and-start solo career, occasionally writing and recording his own songs but mainly singing other people’s, including those unforgettable Simon hits.

The audience comment I most want to hear during next week's Unlimited Festival is: this show has transformed my perception of disability. We got that over and over and over during the first Unlimited Festival, which ran as part of the Cultural Olympiad in 2012. And I want that again. It’s all about making people understand that disability isn’t a negative, awful experience, just a facet of life that can give you as much as it apparently appears to take away. In fact, it just gives you more.

In her book How To Be a Woman, Times columnist Caitlin Moran explains the difference between strip clubs and burlesque shows, and why the latter are perfectly acceptable to feminism.
