Critical, urgent, hard - those are the three words used about the challenge to get the rich to pay more for the arts by the new man at the tiller. He should know. Jonathan Moulds, European President at Bank of America Merrill Lynch, is one of the super-successful, super-wealthy financiers to whom the Cameron government is desperately looking to pick up the slack as they cut back public spending. What the government hopes for is modern-day Medicis - arts patrons who use their wealth to back orchestras, performers, theatres and educational projects - and lots of them.

It’s over 30 years since André Previn left his post as principal conductor of the London Symphony Orchestra. But once you’re part of the LSO’s treasured ‘family of artists’, the orchestra never lets go, year upon year inviting you back for Christmas, New Year, weddings, bar mitzvahs, any occasion going. The same with the violinist Anne-Sophie Mutter – briefly in the last decade Previn’s fifth wife, though they share the same platform with just as much ease now that they’re divorced.

A music broadcaster commented after last night’s concert by the Australian Chamber Orchestra that all the hype, all the talk about the surf-obsessed, free-spirited leader Richard Tognetti, had left her half expecting them to surf onto the stage of the Queen Elizabeth Hall. As they walked on however (decorously, and rather more smartly dressed than most English groups) we were reminded that there’s nothing gimmicky about this ensemble.

Praise be, or slava if you prefer, to Valery Gergiev for honouring new Russian music alongside his hallmark interpretations - ever evolving or dangerously volatile according to taste – of Prokofiev, Shostakovich and Stravinsky. Last LSO season featured some of the less than inspired recent works Rodion Shchedrin has been dredging by the yard. Yet few would begrudge the palm of deep and original musical thought to this past week’s heroine, Sofia Gubaidulina.

It’s almost dark. Frescoes depicting the cycle of life are barely visible. They could be shadows. Waves of sound pulse through the mausoleum of Norwegian artist Emanuel Vigeland. Fiddle player Nils Økland is feeding the 15-second delay with peals that reverberate around the space, folding back into themselves. It’s a spooky, unforgettable introduction to FolkeLarm, Oslo’s annual festival of Nordic folk music.

Niccolò Paganini was the most controversial classical musician who ever lived. Although widely acknowledged to be one of the most brilliant performers of his lifetime, he provoked wildly contradictory opinions amongst his contemporaries and was constantly denounced as a charlatan in league with the devil – a spell in gaol for a paternity suit gave rise to the myth that he had acquired his dazzling technique from a pact with the devil during his incarceration.

You can count on one thing at the Proms: that the sound, if not on this occasion the cut-off point, of the extraterrestrial, wordless ladies’ choir at the end of Holst’s The Planets will scatter stardust through the Albert Hall solar system. Even, that is, if the performance is less than good, and last night’s was better than expected given reports of the same team’s near implosion in Beethoven’s Ninth. Hardly your average programme, either, with an unexpectedly lovely tone poem by featured composer Frank Bridge, and a surprisingly engaging float through the near vacuum of Sir Harrison Birtwistle’s almost new Violin Concerto.

Some violinists just play; others have a voice. Ukrainian-Israeli violinist Vadim Gluzman follows the distinguished line of great Petersburg violinist Leopold Auer - whose 1690 Stradivarius he currently plays - David Oistrakh and Isaac Stern, his one-time mentor.
