Era & Context

Released in 2015, Sleep was an eight-hour composition designed to be listened to while sleeping, created in consultation with neuroscientist David Eagleman. It anticipated the explosion of sleep and wellness audio content while reframing duration itself as artistic statement, challenging concert conventions with overnight live performances where audiences slept in beds.
