Because he dramatised power, Shakespeare never really goes out of fashion. Treatments of his plays do though, and the RSC’s Measure for Measure, a transfer from Stratford set in turn-of-the-century Vienna, feels distinctly slack. The backdrop is supposedly a city filled with refugees, artists, political movers and shakers and members of the upper-class and demimonde.

When it comes to the true jazz legends capable of filling concert halls with faithful fans, whom jazz festival programmers can put on as headliners, the choice is dwindling. Herbie Hancock is one and he does; his Barbican concert is one of the big events of this year’s EFG London Jazz Festival and it had been sold out for months.

So much was fresh and exciting about Michael Tilson Thomas's years as the London Symphony Orchestra's Principal Conductor (1988-1995; I don't go as far back as his debut, the 50th anniversary of which is celebrated this season).

This is one play by Shakespeare ripe for tinkering. It's well nigh impossible now to take it at face value and still find romance and fun in the bullying: the physical and psychological abuse as a supposedly problematic wife is "tamed" into submission. And there have been experiments.

It’s hard to believe that in 1824 there were no fewer than six productions of Weber’s Der Freischütz in London alone. Since then this colourful piece of German Romanticism hasn’t fared nearly so well, disappearing from the UK’s opera houses not just for years but decades at a time.

The Oslo Philharmonic finished its centenary tour of Europe at the Barbican last night with ample proof that it consistently delivers one of the continent’s most well-rounded, and richly satisfying, orchestral sounds. The Norwegians’ modern history may date to 1919, but their stellar reputation only emerged in the 1980s. Then Mariss Jansons, just like Simon Rattle over in Birmingham, shaped a supposedly “provincial” outfit into a regiment of world-beaters.

We have John Eliot Gardiner to thank for an unconventional diptych of Czech masterpieces in the London Symphony Orchestra's current season. He had to withdraw from last night's concert - he conducts Dvořák's Cello Concerto and Suk's "Asrael" Symphony on Thursday - but his replacement, Kazushi Ono, was no second-best.

Verdi, Elgar, Janáček, John Adams - just four composers who achieved musical transcendence to religious texts as what convention would label non-believers, and so have no need of the "forgiveness" the Fátima zealots pray for their kind in James MacMillan's The Sun Danced.

The Barbican’s latest offering – a look at the clubs and cabarets set up by artists mainly in the early years of the 20th century – is a brilliant theme for an exhibition.

Second performances are even more valuable than premieres, composers say, when it comes to launching a piece into the world. Spare a thought, then, for Jan Ladislav Dussek, who has had to wait over two centuries for this prize to be awarded to his Mass in G – really, a Missa solemnis – of a scale to rival Beethoven’s example.
