Dark cabaret may be a simple description of the theme and mood of a cabaret performance, but more recently has come to define a particular musical genre which draws on the aesthetics of the decadent, risqué German Weimar-era cabarets, burlesque and vaudeville shows with the stylings of post-1970s goth and punk music.
The above definition contains all of the elements of Dieselpunk music in that it combines decodence ("aesthetics of the decadent, risqué German Weimar-era cabarets, burlesque and vaudeville shows") with modern sensibilities ("stylings of post-1970s goth and punk music"). The term ‘Dark Cabaret’ first appeared in 2005 with the album titled Projeckt Presents: The Dark Cabaret. The term has since grown in popularity as several band have adopted the label.
An alternative term is 'Brechtian punk cabaret', which was coined in 2003 by Amanda Palmer of the dieselpunk band The Dresden Dolls.
