Replica Sun Machine is the second album by The Shortwave Set. Work began on the album shortly after the release of The Debt Collection. In an interview for Swedish television, singer and songwriter Andrew Pettitt said that by February 2007 the album was completed as far as they were concerned. However, around this time, Danger Mouse heard they were working on a new album, and offered to produce it for them. This led to The Shortwave Set delaying release of the album in order to accommodate Danger Mouse's busy schedule.
