Aqua caught America's attention when they coquettishly beckoned, "Come on, Barbie, let's go party," on their hit 1997 single "Barbie Girl." You're forgiven if you think a song like that has one-hit wonder written all over it. You're also partially right: The guilty pleasure machine did seem to fall off the face of the earth after the track peaked at number seven on the U.S. charts. But the Danish-Norwegian pop-tarts' history actually extends both before and beyond that deliciously silly hit. Claus Noreen, Soren Rasted, Rene Dif and Grawford Nystrom first formed a band called Joyspeed in the late '80s. After achieving mediocre results, they changed their name to Aqua and released Aquarium, their first full-length album, in 1997. Along with a few other Euro-dance hits, that album contained "Barbie Girl," which earned Aqua an international reputation (and a lawsuit from Mattel). Though none of their other material ever hit the heights of "Barbie Girl," Aqua stayed active, releasing a second album before splitting up and later reuniting and releasing a greatest hits album in 2009.
