Query: Great DVD

My favorite singer in the world is Placido Domingo and I love opera. These young men do a great job and bring great music to another level for those who don't enjoy opera. Voices are beautiful. Carlos takes each song to an explosive level and makes the group the best I have heard. I hope they make another DVD. I have tickets to Atlanta in July to see them. B.Hamilton
