Aleya of Cairo has put together a fantastic compilation from the Ahlan wa Sahlan opening gala featuring Katia, Aziza, Soraya and Dina:

You should definitely watch the whole thing (especially Aziza who is just AMAZING). If you’re interested in seeing how Egyptian-style dancers do drum solos there are a few good examples here: Katia at 1:05, Aziza at 7:20 and Soraya at 10:06. When I was writing a post on drum solos it was quite hard to find decent videos so I was pleased to see this.
