performed concerts in Oslo

On 20–22 May 2008, Harket, Furuholmen and Waaktaar performed concerts in Oslo to promote their respective solo material before coming together as A-ha to play ” Train of Thought “, ” Take On Me “, and two new songs, “Riding the Crest” and “Shadowside”, which previewed the new A-ha album, Foot of the Mountain . These events led up to their performance at London’s Royal Albert Hall on 24 May. On 24 April 2009, A-ha surprised their fan base by releasing their new single, “Foot of the Mountain”, premiering that day on Norwegian radio. The single had been completed only the night before. The song is based upon the track “The Longest Night” by Furuholmen, which was released on his album A Dot of Black in the Blue of Your Bliss . The band promoted the German release of the song by playing it during the final of Germany’s Next Topmodel on 21 May at Cologne ‘s Lanxess Arena . Foot of the Mountain , A-ha’s ninth studio album, was released in Europe on 19 June 2009. The album’s material marked a return to synth pop, similar to the band’s earliest work, although the first single (and title track) was not wholly indicative of this. The band collaborated with successful producer Steve Osborne , who has produced albums for such artists as Suede , New Order , Starsailor , Doves , Elbow , and U2 . “What There Is”, an earlier solo track by Furuholmen, was re-recorded for the album.
