Great Civilizations is an album by Jimmy Chamberlin's side project Skysaw. The album was first released digitally under the band's original name, This, on November 1, 2010. The album's only single, "No One Can Tell", was released the same day. However no official release announcement was made even on the band's official website. Downloads from iTunes and Amazon were removed after there was confusion over the band's name. On June 21, 2011, the newly renamed Skysaw re-released the album with four additional tracks as a full-length LP on Dangerbird Records.
The album was entirely written, produced and recorded by the band, with singer Mike Reina as the lyricist.
