Sleep (album)

Sleep was conceived by Richter and his partner, the visual artist Yulia Mahr.[10] It is targeted to fit a full night's rest. Richter talked with American neuroscientist David Eagleman while working on the album's piece to learn about how the brain functions during sleep. Richter stated, "Sleeping is one of the most important things we all do ... We spend a third of our lives asleep and it's always been one of my favourite things, ever since I was a child. ... For me, Sleep is an attempt to see how that space when your conscious mind is on holiday can be a place for music to live."[11]

In the album's credits Richter describes Sleep as an eight-hour lullaby that is meant to be listened to at night. It is scored for piano, cello, two violas, two violins, organ, soprano vocals, synthesizers and electronics. The piece comprises 31 sections in slow tempo. These range from less than three minutes to over thirty, with an average duration of just over fifteen minutes. The sections are variations of five themes.

Sleep was performed in its entirety from midnight to 8:00 AM at the Wellcome Collection in 2015 as the climax of the BBC Radio 3 "Science and Music" weekend.[16] Audience members watched from beds instead of chairs.[11] The performance set records for the longest broadcast and longest live broadcast of a single piece of music.[11] The album was also performed at the Philharmonie de Paris in 2017,[17] and outdoors in Grand Park, Los Angeles in 2018. The Los Angeles performances had 560 beds and were timed so the final movement, "Dream 0 (till break of day)" would occur at dawn.[18][19][20]

Sleep received wide acclaim from contemporary music critics. At Metacritic, which assigns a normalized rating out of 100 to reviews from mainstream critics, the album received an average score of 79, based on 7 reviews, which indicates "generally favorable reviews".[21]

Jon Falcone gave the album a very positive review, stating, "Sleep implores you for companionship and bleeds into itself as it bleeds into the listener. Typing while the fizz of ‘Never Fade Into Nothingness’ plays makes transforms Word documents in an epic dance of black pixels on white light, binary marks scratching into a too-bright glassy reflection. Walking while the echo-drenched monastic vocals of ‘Non-Eternal’ exposes that the world we occupy is haunted is exhilarating and avoiding awkward work colleagues as ‘If You Came This Way’ patters out its motif, that dangles held violin notes over electronic burbles, is to experience the sound of solace itself."[23]

Grayson Haver Currin of Pitchfork Media gave the album a positive review, stating, "At its best, Sleep feels like compositionally rigorous new age music. It’s a place in which you can settle for a while, with or without a pillow, and emerge only when you are ready to rejoin the restive world."[2] Currin was also slightly critical of the release, stating, "Sleep, then, is simply too didactic as a name. It’s a command that tells us how to enjoy something that clearly has other uses. That handle, combined with Richter’s conceit, has turned the record into a kind of clickbait story, too, which seems entirely antithetical to Richter’s point."[2]

As of February 2020 Sleep had peaked at position 44 in the UK album charts, with sales of 40,151.[26] As of July 2020, Sleep had almost 500 million streams.[27]
