Sorry, but I don't think so. I'm not a hundred percent sure but I think it was Mari who sang on Epica not Simone. I think she was always Helena's voice. The collaberation with Simone only came about because Epica (Simone's band) wanted to do a duet with Khan (the song 'Trois Vierges') and so in return they got her to be Marguerite on The Black Halo album.
Maybe you just got confused because Epica is the name of the band Simone is in, but I seriously doubt if it's her on the Epica album by Kamelot.
