The statement from the band reads:
You will find more information about these things very soon on this location.
It seems like Elis has had really bad luck with their vocalists. Simone had only been with the band 8 or 9 months before deciding to depart. I'm not sure why Sandra left, but the band only recorded one CD with her, the rather excellent Catharsis.
I really liked Elis so I am sad to hear this! I loved Sabine, but I also really enjoyed Sandra's voice when she sang with them. I was looking forward to hearing how they sounded with Simone. They had strong, evocative music I enjoyed very much. They will be missed! Best wishes to them all!
