With sleep, relaxation, and ultimately productivity in mind, Endel is an algorithm-powered technology and mobile app that generates audio environments tailored to specific activities, climates, and times of day. As part of a cross-platform system, Endel began releasing digital albums, including Sleep: Rainy Night, in 2019.

Berlin-based Endel was founded by Oleg Stavitsky in early 2018. Creating digital sound atmospheres with the intent to improve listeners' well-being, Endel recordings emerged in early 2019 with albums such as Sleep: Foggy Morning. Part of a five-album sleep series, it resulted in a distribution deal with Warner Music Group and releases targeting other activities. ~ Marcy Donelson, Rovi
