Matthew Chastney is a British composer and producer, releasing music as ‘The Dreamless Sleep’ and creating soundtracks for film, games, trailers and other media projects.

“Just stunning…a name to be listening out for”Sarah Gosling, BBC Introducing

“The minimal and at times whispered vocals function as an instrument in their own right and provide as much colour and depth as the emotive strings. There’s a feel of Ludovico Einaudi about ‘Tarka’, but it paints a much broader canvas both sonically and emotionally.”AnalogueTrash.com
