The hallé

Bristol has a new concert hall, and it’s rather good. The transformation of the old Colston Hall into the Bristol Beacon has been reported as if it was simply a matter of upgrading and renaming. There were probably sound reasons for doing so, but in fact (and despite protests from the Twentieth Century Society) the postwar auditorium has been demolished outright and replaced with a wholly new orchestral hall designed on the best current principles: shoebox-shaped, with much use of wood and textured brick. Butterworth sears his melodies on to the eardrums. Isn’t it weird we still think of the Edwardians as inhibited? Acoustically, it’s extremely fine – not a

Steve Reich describes his Music for Pieces of Wood (1973) as an attempt ‘to make music with the simplest possible instruments’.

It’s consensual, even pleasurable. Why fight it? There’s an Arthur C. Clarke story about a scientist obsessed by the finale of Sibelius’s Second Symphony. He invents an algorithm for musical catchiness and promptly starves
