Nicola Benedetti performs a lot at this year's music festival, swelling the coffers nicely as a result. Her reputation is well founded on the evidence of tonight's concert in a packed Town Hall: I haven't heard such compelling chamber music-making in a long while. Even the long Brahms Quartet at the outset more or less held my attention. A new work for piano trio by Arlene Sierra followed, helpfully trailed by the composer in an interview with the cellist. After the interval came the Shostakovich Piano Quintet, a thrilling performance!
