Aquarium is the debut studio album by Danish-Norwegian band Aqua. The album was released in Scandinavia on March 26, 1997 and in USA on September 9, 1997. Although the group had been together for three years under their original name Joyspeed, their only release up to Aquarium was a single called "Itzy Bitsy Spider". The album is best known for including three UK number ones in "Barbie Girl", "Doctor Jones" and "Turn Back Time", the first of those being a huge hit across the globe and a platinum seller Stateside.
The release of "Barbie Girl" took the four-piece group onto the A-List of European music, meaning that when the album was released a month later in November 1997 pop fans everywhere went out to buy it. The album would peak at number 6 in the UK charts. While not a million seller like "Barbie Girl", the album's second single "Doctor Jones" was released in 1998 and became a UK number one, staying at the top for two weeks in February. The third release "Turn Back Time" would give the group their third consecutive number-one single and further releases "My Oh My" and "Good Morning Sunshine" would peak at number six and number 18, respectively, on the UK Singles Chart. The album has sold 14 million copies worldwide.
