Bristol’s animal magic

It’s the height of the silly season, and the capital glows in the unexpectedly seasonal heat. For anyone who has not forsaken London for the seaside or elsewhere, I recommend the witty diversions of Video Quartet by Christian Marclay, at White Cube in Hoxton Square until 30 August. Four screens project a profusion of film fragments choreographed seamlessly with accompanying soundtrack – clips from Hollywood movies, of singers and musicians (from Hendrix to Sinatra and Callas), concentrating on keyboards, horns and violins.
