lang is that rare performer who, over 30 years as a major-label artist, has matured before our very ears. The Western Canada native launched her career with a blend of country-rock styling and a playfully punk-like attitude.

Anyone lucky enough to attend her very first appearance in the United States, on a triple bill of unsigned artists at New York City's Bottom Line, could hear that she was marked for greatness.
