I like Streisand's voice - her octave range is superb. She has a very clear and pure sound although it has somewhat diminished with her age.
A woman, who never beautiful in the classic sense of the world, gets better and better with age. And a wonderful voice as well. No justice for the rest of us.
Janice,jmb,beyond her being a remarkable artist there's further aspect that distinguishes her from most of her contemporary colleagues (won't name any as the list would become too long): she's no barbie doll.
