Contrast was preceded by a tumultuous period in Tages' career, in which drummer Tommy Tausis left the band for the Spotnicks only days before recording commenced.

[6] The album mixed influences, ranging from soul-pop to psychedelia;[6] their producer Anders Henriksson had assisted them in the studio and incorporated various unorthodox techniques, such as backmasking and reverberation.

[1] Drummer Lasse Svensson (brother of Lill-Babs) of the Stockholm band Hi-Balls received the phone call, upon which he hastily travelled to Gothenburg to meet up with Tages.

[9] Another incident which occurred during roughly the same time was that Tages' record contract with Platina lapsed on New Year's Eve 1966, upon which the band opted out from extending it further.

[12] Tages opted to sign with the label since their releases would be distributed by EMI sublabel Parlophone, effectively making them label-mates with the Beatles.

[13] Guitarist Anders Töpel and vocalist Tommy Blom managed to imitate a thunderstorm by using a piece of sheet metal in the studio's backroom; this sound effect was liked enough by the band to be applied on multiple tracks.

[14] "One Day", composed by Lagerberg and rhythm guitarist Danne Larsson is "another conventional psychedelic song" broken by an "unconventional accordion solo" performed by Henriksson.

[20] It features rain sound effects during the instrumental breaks connecting the chorus and verses, along with what biographers Brandels and Wrigholm call "nonsensical psychedelic lyrics".

[22] Sparsely arranged and largely driven by Larsson's rhythm guitar, it was introduced to the band through Henriksson, who in addition plays glockenspiel on the song.

[23] "House Of Soul Hill" is an upbeat soul-pop song that is "characterized by" the brass arrangement Lars Samuelson's Orchestra plays on it, along with a guitar solo by Töpel.

[24] The album cover of Contrast was a painting illustrated by Håkan Gustaf Carlström, and features photos of Tages taken by Hans Sidén superimposed on top.

[20] A release party was held on the same day the album was issued and it quickly began circulating on Sveriges Radio P3, due to disc jockeys being fans of Tages.

[14] In a review for Show Business shortly after release, Håkan Sandén was brief, stating that "no prior presentation was needed" and claimed that the album was "well-produced pop that would sell itself".

[32] They single out "House Of Soul Hill", "Hear My Lamentation" and "Every Raindrop Means a Lot" as their favourite picks, noting that "they all sound different musically".

[32] The reviewer for Svenska Dagbladet states that Contrast was rightfully promoted by Parlophone, writing that it was one of the better albums to get issued in Sweden, praising Henriksson's production and singles out "Why Do You Hide It?"
