"Cast in Steel" is the tenth studio album by Norwegian band a-ha. The album was released on 4 September 2015 by We Love Music and Polydor. It is the first a-ha album to use the original band logo since Memorial Beach from 1993, and the first album to be produced by Alan Tarney since Stay on These Roads (1988). Following the release of their ninth studio album, Foot of the Mountain, a-ha announced that they would retire as a band. In 2015, however, the band announced that they would re-unite for a two-year period and release Cast in Steel, followed by a world tour to promote the album. Cast in Steel was released on 4 September 2015, shortly before a-ha returns to perform at Rock in Rio for the show's 30th anniversary. Cast in Steel debuted at number eight on the UK Albums Chart, selling 7,828 copies in its first week. It is a-ha's sixth Top 10 album in the United Kingdom.
