Sleepify is a unique and innovative project by the American funk band Vulfpeck, released in March 2014. Unlike traditional albums, Sleepify consists of ten tracks, each a mere 30 seconds long, filled with silence. The band cleverly leveraged music streaming platforms, encouraging users to play the album on repeat while sleeping. This creative approach allowed Vulfpeck to generate royalties from streams, which they used to fund a free concert tour. Sleepify is a testament to Vulfpeck's ingenuity and their ability to think outside the box, making it a memorable and impactful release in their discography.
