For the second year running, Sydney is celebrating the approach of winter with Vivid Sydney, a festival of light, music, and ideas. Brian Eno organized last year’s Vivid Live program and this year husband and wife team Laurie Anderson and Lou Reed have taken the curatorial helm. Anderson’s performance Music for Dogs and Reed’s noise band Metal Machine Trio are among the highlights, but the project that has wowed the crowd is Anderson’s lighting of the sails of the Sydney Opera House.
