Query: What an unbelievably GREAT singer Eva Cassidy is!!!!!!

Eva lives on as one of the absolute best singers that ever sang.Anybody who would say she's not incredibly suberb is just a dead ear.Eva and Genie (Nilsson) are my two favorite singers of all time. They have a mature interpretation of a song that none of these newcomers can match.Don't listen to anybody who says Eva isn't great.EVA IS GREAT!
