BBC Radio 3 will broadcast eight-hour 'lullaby' this weekend in full. Titled 'Sleep', the £25 record is designed to promote good quality slumber and promises a perfect night's sleep.
Composer Max Richter consulted neuroscientist when making the record, which is an unbroken piece of music that he has described as 'my personal lullaby for a frenetic world'.
When Radio 3 sends it out over the airways live and in its entirety on Saturday, it will be the longest single piece of music ever to be broadcast by the corporation.
Discussing the work, Richter says he became fascinated by what goes on 'under the hood' while we're asleep and worked with a neuroscientist to make music that might actually enhance the sleeping experience.
He said: 'I have a sense that while I'm asleep some of the most important work is taking place "under the hood".
'I started talking with the neuroscientist David Eagleman, and it seems that cognitive mental processes really are going on while we're sleeping that relate to our waking life.
He adds: 'I think most creative people would intuitively agree: for instance, if we sleep on a decision we often feel more comfortable about our thinking in the morning. I see the eight-hour piece as an environment, a place to inhabit.'
