US funk band Vulfpeck released a quite unusual album. Their fourth album Sleepify consists of 10 tracks of complete silence.

When they put the album on Spotify, they encouraged fans to play it overnight to help them raise money for a future tour that would be free for fans to attend.

The album didn´t do bad and the band raised nearly $20,000 (£11,700) before Spotify removed the album from their service.
