Bauhaus expanded their style a bit on Mask, particularly by incorporating keyboards and acoustic guitar on songs such as "The Passion of Lovers", and funk rhythms and saxophone on tracks like "Kick in the Eye", "Dancing" and "In Fear of Fear".
The album cover is a drawing by guitarist Daniel Ash. The original artwork for the album was a gatefold sleeve with blue text on the inside and a stark black and white image of the band. On later editions this inside was replaced with white text and a montage from the promotional video for the song "Mask".
"Kick in the Eye" charted at No. 29 on the U.S. Club Play Singles charts.
The 19 October 2009 CD reissue, subtitled the Omnibus Edition, included a remastered version of the original album as disc one, a second disc of B-sides and alternate versions called Singles and Out-Takes, as well as a live CD called This Is for When..., recorded at Hammersmith Palais, London on 9 November 1981.
In his retrospective review of the album, Ned Raggett of AllMusic called the album "arguably even better than the band's almost flawless debut".Trouser Press described the album as "[Bauhaus'] finest achievement".
