'UVA is a London based art practice that combines a wide range of disciplines including sculpture, installation, live performance, and architecture'. Here's some links to examples of their work, including their work with Massive Attack

http://www.uva.co.uk/ UVA are the team behind all of Massive Attack's LED visuals whilst on tour. Chris Bird, Matt Clark and Ash Nehru are interviewed here along with 3D and Daddy G about the their almost decade long partnership on the live tour.

An incredible performance at the Victoria & Albert Royal Museum. A luminous interactive installation has transformed the V&A's John Madejski Garden this winter. Volume is a sculpture of light and sound, an array of light columns positioned dramatically in the centre of the garden. Volume responds spectacularly to human movement, creating a series of audio-visual experiences.
