Longplayer is a very special kind of music that is designed to play for a really, really long time. Think of it like a never-ending song that keeps going and going and going!
The music was created by a group of really smart people who wanted to make something that would last for a very long time, even longer than our lifetimes!
The music is made using computers and special instruments, and it sounds kind of like a mix of different sounds and noises.
People can listen to Longplayer by going to a special place in London, England where it plays continuously, day and night. It's kind of like a big musical clock that keeps ticking and making noise all the time!
Longplayer has been playing for over 20 years now, and it will keep playing for many more years to come! It's really cool to think that the music will outlive us and continue to play for generations to come.
