Aida is a fantastic show. The music is fantastic (written by Elton John and Tim Rice). There are some amazing songs in it, and the story is great. You won't be disappointed.
One of my favorite theatrical actors is one of the leads in the Aida tour. His name is Jeremy Kushnier and he plays Ramades. He's from Winnepeg (and lived in Toronto for a while so it would be a homecoming for him when he's in Toronto). He is one of the most striking, enchanting, and energetic performers I have ever seen onstage. Fantastic, powerful voice.
