Today's Song of the Day is a little unique, in that it's not really a song at all. Icelandic post-rock band sigur rós is currently in the middle of a 24-hour ‘slow tv’ event, which is being broadcast live on Iceland’s national television and streaming globally on youtube. The stream is set to a constantly evolving soundtrack based around elements of new song "óveður"

It started last night at the summer solstice and will be continuing throughout the longest day of the year, a 1332km journey the whole way round Iceland's coastal ring road.

“In a day and age of instant gratification and everything moving so fast, we wanted to do the exact opposite,” says sigur rós’s jónsi birgisson. “slow tv is counter-active to the world we live in, in that it happens in real time and real slow.”
