Maisie Peters has unveiled her latest single, 'Say My Name In Your Sleep' - a stirring and atmospheric collaboration with Marcus Mumford that arrives as the third single from her forthcoming third studio album. Released November 19th, the track finds Peters pushing deeper into a mature, literary-leaning sound - one she says will define the tone of the new record. Co-written and co-produced with Mumford at Real World Studios "in the deep winter", the song grew out of what Peters describes as a "magical and spooky" creative environment.
