They're still bringing Beethoven and Shostakovich to London, enriching the mix a little with the cross-referencing of Alfred Schnittke, but the personnel of the Borodin Quartet have changed again. Patriarch cellist Valentin Berlinsky, there at the start over 60 years ago, passed on his bow to Vladimir Balshin before he died. Balshin is a worthy successor, especially since Berlinsky's tone had become translucent to the point of dematerialising and his successor's is rich indeed, but is "Borodin Quartet" now more a brand name than a vital entity?
