In the Wee Small Hours is the ninth studio album by Frank Sinatra, and was released in April 1955 by Capitol and produced by Voyle Gilmore with arrangements by Nelson Riddle. All the songs on the album deal with themes such as loneliness, introspection, lost love, failed relationships, depression and night life. In the Wee Small Hours has been called one of the first concept albums, right don to the cover, portraying Sinatra on an eerie and deserted street awash in blue-tinged street lights.
Polyphonic explains how Sinatra laid the foundation for the concept album.
