Modernism: A New Decade is the fifth and final studio album by The Style Council. It represented a departure from the band's core genre of pop, to a new one: deep house, which was then being referred to as "garage" (as in Paradise Garage) music by the UK press. However, upon its completion in 1989, the album was rejected by the band's label Polydor, which led to the band breaking up.

The track "That Spiritual Feeling" was re-recorded as a B-side to the first solo single by Paul Weller, his 1991 hit "Into Tomorrow". The full album was eventually released in 1998 on the box set The Complete Adventures of The Style Council; a separate release was authorised and issued on 30 October 2001 and then seen a European 2017 release on colored vinyl along with the other 4 studio albums.
