From the linked article above:
Bellydance traditionally has been considered the visual embodiment of the music. A magical synergy can occur between dancer and musicians that is admittedly missing from performance to recorded music — which is largely what the "Superstars" shows are.
To compensate, Jillina, artistic director and main choreographer for the troupe, is a master at closely interpreting the music with intricate, entertaining movements.
A complaint many Egyptian dancers have had about Western dancers is their musicality. But they aren't referring to how they fit their steps to the music; rather, they feel the Western dancers don't understand and convey the emotional intent of the music. I tend to agree. But still, I'd be interested in seeing this show. I suspect it represents what I don't like about many American dancers, but it would be nice to be proved wrong.
