The Southbank’s artistic director Jude Kelly was out in force at this penultimate weekend of The Rest is Noise festival, delivering little triumphalist, Ryan Air-like fanfares, reminding us how pioneering they had been to programme composers such as Igor Stravinsky, Richard Strauss, Benjamin Britten and Philip Glass - composers who no one had ever heard of before they'd bravely decided to put them on.

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.

French-Canadian pianist Hamelin has the technique and the stamina to play anything, which is why the note-crazy, obsessive “Night Wind” Sonata of Nikolay Medtner buzzed around at the heart of his recital. But between the proud resonance of its many climaxes and the distant voices he showcased so effectively in his own Barcarolle – three movements rather than one, unexplained in a note which simply ignored it – there’s little delicacy in the middle ground.

Berlioz wanted to make the first arrival of his demon onstage unforgettable, with an extreme sound effect - violins and violas marked sul ponticello, strettissimo, starting fortissimo, with interjections from three trombones snarling in minor seconds. In last night's performance of La Damnation de Faust that moment was glossed over. It flashed past as if it had never happened.

This was Sakari Oramo's first concert with the BBC Symphony Orchestra since taking over as chief conductor. Of course he knows the orchestra well already, but it was important to make this a good ’un, and so it was.

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.

Imagine how discombobulated the audience must have felt at the 1962 premiere of Shostakovich’s most outlandish monster symphony, the Fourth, 26 years after its withdrawal at the rehearsal stage. Those of us hearing its natural successor, Schnittke’s First Symphony, for the first time live last night didn’t have to (imagine, that is).

One of the joys of the Southbank Centre’s year-long The Rest Is Noise series has been the opportunity to hear some unusual period pieces among the more standard repertoire. In the case of 200 Motels it is a concert premiere for a genre-bending work which was pulled from its 1971 Albert Hall slot due to complaints about its obscene content.

Back at the Barbican for a new season after a Far Eastern tour, the BBC Symphony Orchestra returned to pull off a characteristic stunt, a generous four-work programme featuring at least one piece surely no-one in the audience woud have heard live before. This time, the first quarter belonged exclusively to the unaccompanied BBC Singers in one of the most demanding sets of the choral repertoire. After which the seemingly humble but dogged and vivacious Marc Minkowski helped create orchestral magic of three very different kinds, defining French composers’ infinite capacity for play.
