More than 100 musicians gathered on the Suffolk coast today for a “joyful performance of organised chaos”.

Choirs, school children and professional musicians filled the streets of Aldeburgh with a “huge mass of sound” at they previewed Musicircus – an even larger collaboration inspired by the avant-garde American composer John Cage.

The full-blown spectacle, which has been billed as a highlight of the 67th Aldeburgh Festival, will feature the largest gathering of musicians the town has ever seen, with 900 performers in a procession through the streets.

Tracy Virr, Musicircus project manager, said today’s preview was a “fabulous” showcase and created a “wonderful” atmosphere. “It was a joyful performance of organised chaos,” she added.

Performers including the Yoxford Singers and festival director Pierre-Laurent Aimard will return on Sunday, June 22, for the full event.
