In our weekly Web Curios newsletter, we have a section for longer reads entitled Long things which are long. There is perhaps no longer thing which is long than Longplayer, the 1000-year-long musical composition from Jem Finer.
Longplayer has an annual day of celebration. That day is today (20/06/19). Starting at noon, there will be a set of performances and talks across east and south London to celebrate Longplayer.
Longplayer started in 1999 and finishes 1000 years later. You still have time to listen to it of course; it's not the sort of thing that you'll find on BBC Sounds. (Imagine how large the file size is for this work).
More here. There's plenty running until the late evening, so don't feel as if you've missed all of the treats.
