It's amazing how long it takes to realise that we're in the 1970s in Michael Grandage's new Glyndebourne production of Le nozze di Figaro. The mansion house suggests that we're in the 18th century. The light and latticework says we're in Mozart's original Seville. The poor villagers that scurry about during the overture preparing the stage for visitors could be from pretty much anywhere Mediterranean and from any century.

With the obvious exceptions of Verdi’s twin masterpieces Otello and Falstaff, Così fan tutte is the most Shakespearean of operas. Centuries before anyone invented the term, it’s nothing less than opera’s most elegant study in sexual politics. Written with the textural richness and emotional reversals of Much Ado About Nothing, it needs acting/singing performances of true depth in order to succeed.

For all but two of its 30 years in business, Garsington Opera has had Mozart in each and every season. He's the nearest this company gets to a resident composer. While everything else at the seasonal operation is in flux, their Mozart is a constant. And as with any long-running relationship, there is a confidence in the coming together of the two of them that usually makes any new Mozart production at Garsington one of the Summer highlights. This year was no exception. 

Lightness. Tenderness. Grace. These are not words you normally associate with Barenboim's pianism - not these days. But they were exactly the thoughts running through my head while listening to his performance of Mozart's C minor piano concerto last night at the Royal Festival Hall. Subtly marshalling his Staatskapelle Berlin from the keyboard, Barenboim was a wholly transformed figure from the ingratiating, lollipop-distributing showman I'd seen at the Tate Modern last year. 

Norman Lebrecht, the seasoned and ever-alert musical commentator, thinks he and his readers may have uncovered someone making a very good stab at being Mozart. Three pieces have been discovered on the internet DIY-video channel being played by a pianist whose face can't be seen, all purporting to be new or obscure works by Mozart, Haydn and Mendelssohn.

To Charles Rosen it was a work of "rarely redeemed dullness". The wife of Emperor Leopold called it "German rubbish". It's pretty obvious why so many have objected to Mozart's final opera La clemenza di Tito. Tunes (memorable ones) are by and large lacking, which is odd for Mozart. The overture is not something you'd want to hear on its own. And the work's great solo arias are unwieldy in form (though fascinatingly so) and tricky to sing and separated by the vast wastes of a notorious recitative.

Classical music and sport: should they spend more time together? The idea was posited more than 20 years ago that football and opera made for ideal bedfellows, so long as the football was being played in Italy and the operatic aria was Nessun Dorma, sung by Pavarotti. Since then no major tournament or Olympiad passes by without the BBC making the effort to hoik improving classical sounds into the broadcasting mix.
