I think the majority of dancers who claim to be Egyptian style are not. It's really depressing and I wish more dancers did their research.
WHO is Badia of Egypt? Is she referring to Badia Masabni of LEBANON??
Badia Masabni may have lived in Egypt in her later years but she was very Lebanese.
As for torso isolations being key to Egyptian style dance...uh, NO. Where'd she get that idea?
We have some dancers in my area professing to teach Egyptian style complete with swords, isis wings, veil, double veil and floorwork. hehehe
