Brandy was fearless at the beginning of her career, which equated to some really great live performances. She really added some great ad-libs during this time.

In the 1st performance she hit all those really high pretty, fluttering bird-like notes that she doesn't hit anymore, now that her voice is gotten much deeper in her adulthood.
