Sleepify is a unique and innovative project by the American funk band Vulfpeck, released in March 2014. This isn't your typical album; instead, it's a creative and strategic collection of ten tracks, each lasting roughly 30 seconds, filled with silence. The band ingeniously leveraged this unconventional release on Spotify, encouraging fans to play it on repeat overnight while they slept. The genius behind this move was to generate royalties from the streams, effectively crowdfunding a free concert tour. Sleepify stands as a testament to Vulfpeck's innovative spirit and their ability to think outside the box, making it a memorable and impactful release in the music world.
