Three cheers for good old Albert, natural laugh-out-loud heir of Verdi’s Falstaff and Puccini’s Gianni Schicchi, and the best possible way to mark creator Britten’s being one hundred years and one day old. Youth has its day in both those earlier masterpieces, but the lovers are subordinate to the middle-aged comic protagonists. Here they're the equals of a hero who is no scamster but a shy grocer’s boy who busts out drinking and worse to loosen the apron strings of a prim community.

“Translated Daughter, come down and startle/Composing mortals with immortal fire.” So W H Auden invokes heavenly Cecilia, patron saint of music, and it seems she did just that with Benjamin Britten, who set Auden’s text for unaccompanied choir and happened to be born on the saint’s day 100 years ago.

How many reviews of War Requiem do you want to read in Britten centenary year? This is theartsdesk’s fourth, and my second – simply because though I reckon one live performance every five years is enough, Rattle’s much-anticipated Berlin Philharmonic interpretation fell almost entirely flat, and I wanted to hear at least one good enough to move me to tears.

Pure, unorthodox genius: the terms apply both to the three works on the Belcea Quartet’s programme – Haydn at his most compressed, Britten unbuttoned and sunny, Shostakovich hitting the tragic heights – and, if the term “genius” can be applied to re-creative artists, to the players themselves. Corina Belcea could surely have as big a solo career as violinists like Julia Fischer and Lisa Batiashvili, but she chooses to work with equally committed colleagues Axel Schacher, Krzystof Chorzelski and Antoine Lederlin in what is by and large a greater, wider repertoire.

From the strange, stuttering opening to its elegiac, drawn-out coda, this is an exquisite, lovingly realised staging of Britten's last opera. It's so good that it amplifies any doubts that you might have about this peculiar, distinctly unlovable piece.

“Aren’t you sick of Britten yet?” asked a colleague three-quarters of the way through the composer’s centenary year. Absolutely not; there have been revelations and there still remains so much to discover or re-discover. Yet re-evaluation can sour as well as sweeten; acclaimed works in the canon may turn out less good than remembered.

Britten’s innate theatricality shines through every single bar of his War Requiem. Atmosphere, drama, suspense, and high emotionalism are to a greater or lesser degree written into the piece (something which the naysayers always latch on to).

A “world premiere” of music written by Benjamin Britten just over 70 years ago? Whence this treasure trove of long-lost musical gold? Well, under the title of An American in England, in 1942 Britten wrote the score for a BBC/CBS co-produced series of six radio drama documentaries for transatlantic transmission to make Americans appreciate this country’s war effort. It was jointly commissioned by the War Office and performed by a 62-piece RAF band in full dress uniform.

Interviewed live just before his Proms performance of Britten’s Serenade, Ben Johnson was asked the usual question as to whether the composer wrote especially well for the tenor voice. “He writes amazingly for every instrument,” came the reply. If we needed a single-programme testament to that special genius, this all-Britten celebration from Vladimir Jurowski and his London Philharmonic Orchestra was it. In addition to the two billed soloists, there were at least a dozen from within the orchestra who proved the point.

For Londoners unable to travel up to Aldeburgh – or, now, to Leeds for the revival of Phyllida Lloyd’s Opera North production – this was the only chance in Britten centenary year to be blitzed by his seminal masterpiece. After the phenomenal success of the Proms’ Wagner semi-stagings, even the craft and sure-footedness of Daniel Slater’s direction here was never going to be a substitute for Grimes in the opera house (or on the beach), serving only to show that this is a supreme music drama least happily separated from the theatre.
