"Lost & Not Found" is a song by British record production duo Chase & Status, featuring vocals from British singer Louis M^ttrs. It was released on 26 June 2013 as the lead single from their third studio album Brand New Machine. The song was originally due to be released on 30 June, but was included on Clubland 23 which was released on 24 June and the release date was brought forwards. Due to this incident, the song title was changed to include the "not" from the second half of the chorus.
