I'm looking for a pop song - years most likely 2000 - 2005

I was a small child then were the days when the Internet was not yet widely available and music between computers circulated on CDs.

There were recordings of concerts where three girls danced, sang in English, depending on the songs with confetti or a huge amount of rose petals falling on the stage. I know the information is scarce, but anyone associate any supergroups from those years that may have been Pop/techno/dance music in general
