Danish/Norwegian Eurodance-pop group. Formed in 1995 in Denmark. Best-known for their 1997 breakthrough single "Barbie Girl". They achieved huge success across the globe in the late 1990's with their debut album "Aquarium", and early 2000's with their second album "Aquarius", and holds the record as the best selling Danish band with around 33 million records sold.

Aqua disbanded in July 2001 and then reunited in October 2007, announcing a new tour in 2008 and a upcoming compilation. In June 2009 "Greatest Hits" was released which included three new songs.

In 2011, Aqua released their third studio album "Megalomania". This album shifts from a more bubblegum pop and eurodance style to a more mature electropop and dance-pop.

In 2018 Aqua returned as a trio (minus Claus Norreen) with their single 'Rookie', and have done many tours since.
