Atomos is the second album by ambient music duo A Winged Victory for the Sullen. The album was released on October 6, 2014 on the labels Erased Tapes and Kranky. The album contains the music from Atomos, a dance piece by choreographer Wayne McGregor and his company Wayne McGregor Random Dance. The music was recorded in Summer 2013, in studios in Brussels, Berlin and Reykjavik. Regarding the recording process, pianist Dustin O'Halloran has commented: "We never imagined 2013 would be such an explosively creative year. The first record took us two years from start to finish, but in the micro span of time over last summer we were able to change the formula for the way we write, record, and let go. It was incredibly liberating." The dance piece premiered at Sadler's Wells, London, on 9 October
