@dorkwad ,
Thanks for bringing up Rickie Lee Jones. I don't know how I could have forgot to mention her. Saw her live but can't remember if it was Rickie Lee Jones or Pirates, at the Pantages (I think). 

She was still doing heroin back then and mumbled between songs but when the music started, her voice simply drowned out the horn section. My oh my, the pipes on that girl.

All the best,
Nonoise
1+ for Jennifer Warnes, no quarrels w Linda R or Emmylou, but no love for Gillian Welch or Amber Rubarth?
