I had the privilege of seeing Pavarotti perform a few years ago. He was a powerhouse, for serious. The Three Tenors got a lot of stick for "commercializing" opera, but I personally never saw it that way. If you ask me, they made it more accessible. I was never really into traditional opera, but I had The Three Tenors playing in my car. And I think Pavarotti's duets with various pop stars probably introduced a lot of people to opera who otherwise wouldn't have given it a second thought.
