A-ha is a Norweigian synth-pop group formed in 1982. All ten of their studio albums have either reached #1 or #2 in Norway – the first three also reaching the top 10 in several countries across Europe – with a total of over 35 million sold worldwide. They became a ‘teen pin-up band’ and were followed by screaming, enthusiastic fans. In 2012, all three members were appointed to knighthood in Norway for their contributions to music.
A-ha achieved their biggest success with their debut album Hunting High and Low in 1985. That album peaked at number one in their native Norway, number 2 in the UK, and number 15 on the US Billboard album chart; yielded two international number-one singles: "Take On Me" and "The Sun Always Shines on TV"; and earned the band a Grammy Award nomination as Best New Artist. In the UK, Hunting High and Low continued its chart success into the following year, becoming one of the best-selling albums of 1986. The band released studio albums in 1986, 1988, and 1990, with single hits including "Hunting High and Low", "The Living Daylights", "Stay on These Roads" and "Crying in the Rain". In 1994, after their fifth studio album, Memorial Beach (1993), failed to achieve the commercial success of their previous albums, the band went on a hiatus.
The band has released ten studio albums, several compilations, and four live albums. In less than a year, during 2010, the band earned an estimated 500 million Norwegian kroner from concert tickets, merchandise and the release of a greatest hits album, making them one of the 40–50 largest-grossing bands in the world. The band was listed in the Guinness World Records book for having the biggest-paying rock concert attendance; they drew an audience of 198,000 at Maracanã Stadium during Rock in Rio festival. Another record for the band is for singer Morten Harket, who was (and is still) listed in the Guinness World Records book in 2001 for the longest live note held; he held a note in "Summer Moved On" for 20.2 seconds. Their exact sale figures are somewhat controversial: According to their label Rhino Entertainment they have sold 55 million records, other sources even list more than 100 million sold units.
