Query: ONE OF THE BEST FEMALE ARTISTS EVER

Sarah McLachlan's voice is one in a million. It can bring tears to the strongest of eyes. Live CDs usually get on my nerves,but this just too great of a collection worry about things like audience noise. Mirrorball contains such beauties as "Angel." This is definately one of the most emotional songs ever written. "I Will Remember You" is a tear-jerker if ever there is one. You absolutely can not go wrong with a treasure like Mirrorball.
