The album is seen as a revolution in the Hall & Oates sound, paving the way for future blockbusters like Private Eyes. It was the first album that Hall & Oates produced by themselves, working in conjunction with renowned engineer Neil Kernon.
The original LP album cover was in black & white and had several variations with the duo in different poses and the half circle, sound-like waves were embossed & raised; a marketing technique commonly used in late '70's record sleeve packaging. It was subsequently replaced in 1981 with a color photograph of the duo, excluding the original pose of Hall "escaping" from his white trench coat-like jacket. The album was re-released in 2004 as a remastered version with a slightly different cover photo but no additional tracks. The Japanese re-release version had two extra tracks: a remixed version of "Kiss on My List" that had previously appeared on the album 12 Inch Collection 2 and a remix of "Everytime You Go Away" that was also available on the album The Ballads Collection - RCA 100th Anniversary Series.
