‘The Four Points are Thus Beheld’, a Blakean title for a show by sound artist Richard Knight, delivers a particular mélange of sounds and spoken word from Sun Ra to Patti Smith, Cecil Taylor to Ut, doo-wop and afro-futurism. Add in sound art work by Salomé Voegelin, Antye Greie and Felicity Ford in any typical show and you have some idea of what to expect.
