There are at least 15 different artists named Iris:
1) An American synthpop band formed in 1993.
2) A Romanian hard rock group formed in 1977.
3) A chilean experimental hip-hop band.
4) An instrumental band featuring Marillion members Ian Mosley and Pete Trewavas.
5) A Spanish singer from Barcelona.
6) A music group specialized on Touhou and it’s music.
7) An Australian pop-rock band.

A German progressive band.
9) A Portuguese hard rock band.
10) A British band from Derby.
11) A Hungarian metal band.
