London's only Lighthouse illuminated for the first time in 150 years by new Artangel installation: Sonic Ray

The lantern room of London’s only lighthouse will shine for the first time since the late 19th century Sonic Ray – a new installation produced by Artangel celebrating the 1,000 year-long musical composition Longplayer, created by artist Jem Finer.

Sonic Ray is a new large-scale installation that projects the sound of Longplayer through a beam of light across the Thames between two locations linked via a short boat ride. You can start your journey at either the Trinity Buoy Wharf Lighthouse or Richard Wilson's walk-on sculpture 'Slice of Reality' on the Greenwich Peninsula.

Supported by the Trinity Buoy Wharf Trust.

Originally planned for 2020, Jem Finer’s Sonic Ray was amongst many arts events worldwide that were repeatedly rescheduled due to the pandemic. During the months that have elapsed, time appears to have been experienced differently, enriching the meaning and value of Longplayer as a paradigm for change. As inexorable as the tide or the movement of clouds, Longplayer seems more than ever a lodestar for our times with Sonic Ray as its signal of hope made manifest.
