Anniversary years are essential to classical music, shaking up our regular rhythms of programming and listening every year with new emphasis and new discoveries. While Britten, Wagner and Verdi have all had their moments in 2013, it is Witold Lutosławski who may yet emerge as the unlikely hero. Last night his exquisitely stark Cello Concerto held its own against a major Adès premiere, itself written in memory of the elder composer – surely one of the 20^th century’s neglected greats.

As good old Catullus put it, I hate and love, you may ask why. No doubt it's my job as a critic to probe such difficult responses to Britten's Canticles. Why am I so repelled by the sickly-sweet lullaby Isaac sings just before daddy's about to put him to the sword in Canticle II, then so haunted by the sombre war requiem of Britten's Edith Sitwell setting, Canticle III? Ambivalence about Ian Bostridge's weird dominating presence and Neil Bartlett's marshalling of five responses to the five very different narratives doesn't make it any easier.

"Britten or Poulenc?" The question may seem a fatuous one, geared to the 100th anniversary of the Englishman's birth and 50 years since the Frenchman's death. Yet it certainly livens up what would otherwise be the usual dreary artists' biographies, presented with typical elan in this year's Cheltenham Music Festival programme book. "Has anyone said Poulenc in response to this?" asks pianist James Rhodes.

Britten’s coronation opera, paying homage less to our own ambiguous queen than to the private-public tapestries of Verdi’s Aida and Don Carlo, is not the rarity publicity would have you believe, at least in its homeland. English National Opera successfully rehabilitated it in the 1980s, with Sarah Walker resplendent as regent. Phyllida Lloyd’s much revived Opera North production gave Josephine Barstow the role of a lifetime, enshrined in an amazing if selective film.

In Britten’s centenary the Aldeburgh Festival has come up with two mesmerising opera happenings. The innovation is to stage Peter Grimes on the town’s beach, a few hundred yards from the composer’s beachside Aldeburgh first home, amid a splurge of decaying fishing boats. The daring recreation is to present all three of his orchestrally bewitching 1960s Church Parables in their original setting, Orford Church, where Peter Pears famously created three roles: the distraught Madwoman in Curlew River, haughty Nebuchadnezzar in The Burning Fiery Furnace&n

First things first. There are limited tickets still available for this run of Peter Grimes on Aldeburgh beach but there won’t be for long, so move fast. You can read the rest of this review later; the next few minutes could make the difference between experiencing one of the most memorable performances of your life and just finding out what you’ve missed out on.

How often should a music-lover go to hear Britten’s most layered masterpiece? From personal experience, I’d say not more than once every five years, if you want to keep a sense of occasion fresh. So how often should an orchestra play it? Sir Simon Rattle and his Berlin Philharmonic decided they could manage three nights in a row towards the end of their 2013-14 season. At the first of the performances, it already felt like a lot might have been kept in check.

Austere, beautiful, heartbreaking, streaked with genius - that goes for both Benjamin Britten’s last opera Death in Venice and Deborah Warner’s remarkable production of it for ENO, returning all too briefly to the Coliseum, with a superb central performance. Besiege the box office for one of the four remaining performances if you want to see contemporary operatic art refined to its most personal and powerful.
