A multitrack masterpiece. Mixed for 5.1 surround sound and stereo from the original analog master tapes by Pink Floyd Producer/Engineer James Guthrie. As they did with their previous release, Dark Side of the Moon, Pink Floyd made great use of studio effects for this, their ninth album overall. The record's winding soundscapes are perfect for the canvas of multichannel SACD. Spacious and airy, the record breathes like a living being.
