I think bht hit the nail on the head. The interpretation is exactly as I see it

She didn’t have to be as good as anyone , she was very good as herself and her clear crystal voice pierced a generation of listeners through their hearts and into their heads , a sound this collection brings back and makes real. You can forget how good she was but every so often it is right to remember.

Judy Collins was not as original as Joni Mitchell; her voice was not quite as good as Joan Baez (though some may disagree); her Dylan interpretations were good but not revelatory. Still, Judy Collins’ body of work, anthologized here, includes moments and touchpoints for a generation or two.
