Jem Finer, born 1955, has been a bandmember of The Pogues.
In 1999 he installed a composition, called Longplayer, that started on January 1st 2000 and will not repeat before December 31st 2999. In other words, it will last for at least one thousand years, much longer than John Cage´s ORGAN²/ASLSP in Halberstadt (Germany).
Longplayer is physically located in a lighthouse in London, Trinity Buoy Wharf, where the river Lee flows into the Thames.
The lighthouse is worth a visit. But you can listen to Longplayer everywhere in the world, it is online.
