"Every day, the BE OPEN Sound Portal will host one of five leading
musicians and sound artists, each of whom has been specially
commissioned to create a unique soundscape. Expect a range of vibrant
sonic and musical responses, from the sounds of glaciers breaking up to
electronic music composed by one of the top musicians in this field.
Cocooned from the external noise and bustle of the city, the BE OPEN
Sound Portal allows visitors to experience a very different environment,
one created by sound alone." via http://www.londondesignfestival.com/events/be-open-sound-portal
