Ragnar Kjartansson & The National

Here’s what happened: You meet someone and play them your current favourite song, only to find out that it’s their favourite, too. Yes! Then you listen to it forever – or at least for six hours. If you don’t just have a weakness for pop music, but also for melancholy, and if you’re also a visual artist called Ragnar Kjartansson, then you might ask the band (in this case, The National), whether they would like to play the song (in this case, “Sorrow”) in New York’s MoMA PS1 non-stop for six consecutive hours – and then you make a film about the whole thing.
