Twenty young conductors have been shortlisted to compete in the Donatella Flick/London Symphony Orchestra Conducting Competition in late September. The top prize is a cash award of £15,000 and an attachment to the LSO as Assistant Conductor.

The 20 comprise four from the UK - Joolz Gale, Ben Gernon, Jonathan Lo and Gemma New - Irishmen Daniel Stewart and Robert Tuohy, three from Spain, two each from Italy, France, Greece and Germany, a Hungarian, an Austrian and a Portuguese.

Even in this age of desperate reality TV, you have to have doubts about any show that tries to convert “celebrities” into serious contenders in an alien field. Is it serious or a padded-out joke? To an extent we’ve been here, or close by, before. Can it be four years since the first Maestro came to our screens, featuring eight celebrity contestants vying for the chance to wield the baton at the Proms and, eventually, launching the winner, Sue Perkins (narrator this time), on a new career as a comedy conductor?

Donatella Flick, one of Britain's most important arts patrons, is furious. "Madness!" she cries in her lush Italian voice. "This is a country that was fantastic, and now there's a demolition going on, bit by bit!" We're sitting in Sir Winston Churchill's old drawing room - now her drawing room - near Kensington Gardens, and I would give a lot to see David Cameron flinching on her huge black sofa as he got a withering dressing-down.

Many of Italy's artistic institutions may have tottered or crumbled during the Berlusconi years, and the more capable new man in the Palazzo Chigi can only offer painful sticking plaster, yet one major orchestra has never sounded better.

He's just launched the last of seven phenomenally successful seasons as music director of a transfigured Royal Scottish National Orchestra. Subscriptions for the Edinburgh and Glasgow concerts have doubled, attendances soared, and Stéphane Denève is a popular figure not just in the musical world but also in Scotland's wider cultural scene, not least as measured by his special guest appearance in the Sunday Post's long-running cartoon series The Broons.

Newly knighted with the Royal Norwegian Order of Merit for his services to the Bergen Philharmonic Orchestra, American conductor and pianist Andrew Litton is a musician who believes in the nurturing of long-term orchestral relationships: eight years as music director in Bergen, with the contract recently extended to 2015, and an equal length of time before that in Dallas have reaped their rewards.

Born in Russia in 1972, the London Philharmonic Orchestra's principal conductor has galvanised the capital's music scene with some of the most thoughtful, groundbreaking and carefully prepared concert programmes today. His operatic credentials at Glyndebourne have been no less impressive, with attention to the right individual style in Verdi, Wagner, Rossini, Tchaikovsky and Mozart, among others.

Robin the boy wonder, as he was somewhat patronisingly dubbed during his prodigious rise to conducting stardom, will make a bracing Batman for Glyndebourne Festival Opera when he takes over from current music director Vladimir Jurowski in January 2014.

Honour your senior master conductors: there aren't so many of them left now. Abbado and Haitink spring most readily to mind, but orchestral musicians may also nominate Neeme Järvi, who celebrated his 74th birthday last week. A passionate patriot and the man his country voted "Estonian of the Century" in 2000, he proudly sports the colours of the national flag in concert attire by virtue of a natty added blue handkerchief.

Anyone who's attended an Aurora Orchestra concert at Kings Place will know that twentysomething conductor Nicholas Collon - oddly, the birth date seems elusive - is a force to be reckoned with. When he speaks, he looks as if butter wouldn't melt, but in action his technique is disciplined as well as sufficiently free to get the flexibility he needs. So the London Philharmonic Orchestra has made an excellent choice in appointing him as assistant conductor to Vladimir Jurowski from the beginning of the 2011-12 season.
