Fluid and engaging, 7 Hertz fluctuate and mutate live before your very ears. incorporating all or none of the following instruments - basson, violin, voice, double bass, french horn, glockenspiel, clarinet, mandolin, trumpet - they improvise glorious pieces with total, beautiful spontaneity. With imaginations that rival those of Tom Waits and Stravinsky this is modern "classical" music that writhes and soothes.
