The Brodsky String Quartet is probably the most well-known string quartet in Britain, largely due to its genre-busting work with such diverse partners as Elvis Costello, pianist Maria Jao Pires and Bjork.

At its Brighton recital, it was joined by viola player John Metcalfe to become a quintet and to perform Brighton composer Martin Butler's new piece, Sentinels.

Butler, a professor of music at Sussex University, is currently enjoying a period of stardom. He has had an opera produced at English National Opera and, from September, will become the Brighton Philharmonic Orchestra's first "composer in focus". Many of his works will be performed in the Dome Concert Hall over the next two years.

Butler's music is accessible and pleasant, akin to a march which never slows or quickens. Other works included Stravinsky's Concertino, a masterly account of Shostakovich's Ninth String Quartet and Mozart's epic G Minor Quintet.
