One miracle of musical performance is that a work you’ve loved for years can be revealed as never before in an outstanding interpretation. That happened to me last week at the New Ross Piano Festival when 22-year-old pianist Magdalene Cho turned us upside down in Bach’s Sixth Partita. It happened again last night when Peter Whelan and his Irish Baroque Orchestra hit 1788 with one of the three symphonic masterpieces Mozart composed in a single summer, the 39th.

It amuses me that Dubliners dress up in Edwardian finery on 16 June. After all, this was the date in 1904 when James Joyce first walked out with Nora Barnacle and, putting her hand inside his trousers, she “made me a man”. So it’s National Handjob Day. But Bloomsday too, celebrating the jaunts of Stephen Dedalus and Leopold Bloom over 24 hours around Dublin, the song of a great city in Ulysses.

If, like me, chamber music isn’t your most frequent home, there are bound to be revelations of what for many are known masterpieces. Mine in recent years have involved Brahms, a composer I love more the older I get: the Second, A major, Piano Quartet, much less often heard than No. 1, at the 2018 Hatfield House Chamber Music Festival, and, last Friday, his First String Quartet from the Cuarteto Casals, also new to me, in an airy room looking out on Dublin’s Glasnevin Botanic Gardens.

In Dublin, a city that has changed more than most in the last 30 years, a young woman, with an English accent that is expensive to acquire, is cycling through sexual partners. We eavesdrop on their conversations, witness the physical intimacy fade as the psychological intimacy hesitantly grows, in that strange vacuum in which you realise that you know everything and nothing about the person in front of you.

Never make your mind up too soon about any large-scale work by a genius. Back in 2010, I had my doubts about James MacMillan’s first Passion, hearing in the impact of Colin Davis’s Barbican performance a halfway house between the composer's shattering best and his more contrived side.

When you’ve already come as close as possible to perfection in the greatest masterpiece, why risk a repeat performance with a difference? Because Bach’s St Matthew Passion needs to be an annual fixture without routine, and because inspirational IBO director Peter Whelan can be guaranteed not only to recapture the magic but to try a few new things, and to choose new soloists with fine judgement.

On paper, it was a standard programme with no stars to explain how this came to be a sellout concert. But packed it was, an audience of all ages which sat with concentrated awe through the spellbinding slow movement of Brahms’s First Piano Concerto and went wild at the end of Berlioz’s Symphonie fantastique. Both works were groundbreaking at the time, sounding absolutely fresh here with the passion and precision awesomely well balanced by conductor Lio Kuokman.

So much looked promising for Irish National Opera’s first Wagner: the casting, certainly, the conductor – Music Director Fergus Sheil knows and loves this music – and the venue (the Libeskind-designed Bord Gáis Energy Theatre, proven ideal for Richard Strauss). How could a production go wrong with such a theatrical romantic tale, a pioneering music-drama for its time (1843)? All too easily, it seems, by either coming up with inappropriate business or letting the singers stand and deliver.

In one sense it was a New Year’s Day “nearly”, just stopping short of giving us the already great Irish lyric-dramatic soprano Jennifer Davis in the music of the man she was born to sing, Richard Strauss. Berlin will witness her Arabella shortly, but the one Bavarian intruder in the otherwise all-Viennese carnival yesterday afternoon, the Moonlight Music from Capriccio, stopped before the Countess’s final scene.
