The album's atmosphere, as Chris Lowe recalled in 1993, contrasted with the vibrant rave scene of the era. Despite their intention to create an uplifting record, the result was something more melancholic. Tennant agreed that there was a component of sadness in Behaviour, and that sad songs often prove more interesting to compose. Production spanned May and June 1990, encompassing studios in Munich and London such as Sarm West and Abbey Road, where orchestrations and strings were added. The album, originally released on October 22, 1990, included tracks like Being Boring and Jealousy. A special Japanese edition even offered an additional mini CD, exclusive artwork, and printed lyrics in a special box.
Over time, Behaviour was reissued as part of the Behaviour/Further Listening 1990-1991 series. This digitally remastered version included a second disc with B-sides and unreleased material from the era, such as Miserablism, a satire on Morrissey that was almost included on the original album, and DJ Culture. These tracks, along with Was It Worth It?, became singles that appeared on later compilations like Discography: The Complete Singles Collection.
