A powerful beam of light projects the sound of Longplayer, a 1000-year long musical composition that echos around London's only lighthouse, across the River Thames for Artangel's Sonic Ray.

The sound of Longplayer is encoded into an earie green laser and transmitted at the speed of light from the Faraday Lighthouse on Trinity Buoy Wharf, across the Thames to Richard Wilson’s nautical sculpture Slice of Reality, on Greenwich Peninsula's foreshore. A new temporary listening post lies aboard the divided ship and a short ferry ride connects the two locations, turning the sound of Longplayer into a bridge of light across the Thames.
