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.

Anyone who saw or attended this year’s Last Night of the Proms will know that Marin Alsop is a born communicator with a wry sense of humour. Another of those youthful crowds The Rest is Noise festival keeps attracting gave her a hero’s welcome last night, and she responded with easy compering.

If ever there were a week for London to celebrate Poulenc in the lamentably under-commemorated 50^th anniversary year of his death, this is it. Two major choral works and two fun concertos at last join the party. But if Figure Humaine and the Concerto for Two Pianos look like being well positioned in the BBC Symphony Orchestra’s Barbican programme on Saturday, Yannick Nézet-Séguin’s chosen two were the victims of his own success in Prokofiev interpretation.

Still only a year out of college, the diversely gifted trumpeter, composer and bandleader Laura Jurd has risen rapidly to prominence, enterprisingly bypassing the ritual of hanging around to be noticed by creating her own scene and ensembles. One of these, the Chaos Collective, this week curated a small festival in which another, the Chaos Orchestra, last night performed a range of new work. Most hotly anticipated were the arrangements of Stravinsky’s Rite of Spring, celebrating the centenary of its first performance.   

For the Leipzig Gewandhaus Orchestra’s second residency at the Barbican Centre Riccardo Chailly pulled focus on an entirely new sounding Brahms. Gone were all those bad performance practices, bad habits, from the early 20th century, gone was the lingering romanticism, the willful soupiness, and in with a vengeance came a classical rigour, a lean and hungry vitality.

I’d not previously identified much comedic potential in Mahler’s gargantuan Sixth Symphony, a piece which would feature prominently in many people’s lists of most depressing works. Which presumably explains why this astonishing concert wasn’t a sell-out, and why the prevailing gloom prompted a fair few audience members to make an intrusive dash for the exit before the double basses sounded their final pizzicato.
