Wolfgang Rihm Day, Barbican

Isserlis performs a winning new cello concerto from the German master

It's hard to miss German composer Wolfgang Rihm. He has an enormous head. There it is, bulging from his giant frame, a big, friendly grin slapped onto it while he wanders around the Barbican on his celebratory day, none of it going to waste. Listen to his prolifically combustible music, the million and one ideas hurtling about with the energy of a school playground and the intensity of a burning sun, and you soon realise that all that cranial space is probably quite necessary.

BBC Symphony Orchestra, Marc Minkowski, Barbican

Smashing performance of Pergolesi's Stabat Mater in his anniversary year

It always repays to push a world-class orchestra beyond their comfort zone. The BBC Symphony's sound emerged from the refashioning hands of period specialist Marc Minkowski like a naked body from a cold shower: convulsively invigorated and invigorating all those that knocked into it. It was a joy to hear: the best, most intriguing period-playing I've heard for quite a while. For sure the orchestra were more comfortable in Stravinsky's Pulcinella, which went off like a spinning jenny, but the sounds Minkowski managed to elicit from the players in Pergolesi's Stabat Mater chilled the blood. More on all that later.

BBCSO, Bĕlohlávek, Barbican Hall

Third instalment in Martinů cycle dazzles and disturbs

Nothing stays the same for long in the hypersensitive symphonies of Bohuslav Martinů. A pastoral idyll accelerates to fairground mania before dropping off the merry-go-round, rapture fades in a single bar and victory may be snatched out of the jaws of brutal conflict at the very last second. The Czech exile's rich, compressed works of the 1940s, when he was living in New York and pining for the European scene he loved so dearly, are winning new admirers. A packed Barbican audience for the third in his ideal interpreter Jiři Bĕlohlávek's symphonic cycle with the BBC Symphony Orchestra enthusiastically demonstrated the phenomenon.
