Aida - 2001 Studio Cast

This recording is billed as the 'Broadway Cover Cast', but does anyone know who the singers are? I think I've identified (by her name alone) Franne Calma as Amneris, and the other singers seem to have fairly thick Northern European (Dutch?) accents. Any ideas?

I have a Dutch release of the cd from 2001 by Weton-Wesgram, the 'booklet' mentions that it's licensed from TRC Music B.V., which are both Dutch companies. The backcover mentions it's a product from the UK. But it feels like it could be Dutch singers indeed. I have no more information.
