Supersister Super Sister, Super Sisters, Supersister Projekt 2019, Sweet OK Supersister, Sweet Okay Supersister, Sweet Okay Supersisters
Dutch progressive rockband, existed from approx. 1970-1974. Reunited in 2000, but in 2001 Sacha van Geest unfortunately died of a heart attack which meant the end for Supersister. Then they planned for a reunion as a three-piece band in 2010, but then Ron van Eck unfortunately died of cancer in 2011. In 2019 Robert Jan Stips asked a bunch of old musical friends to make new Supersister-styled music which led to the band now being called Supersister Projekt 2019.
