I'm trying to find more nice music. Any recommendations? Here are some artists I really like:
Joni Mitchell
Patricia Barber
Frente!
The Sundays
The Cranberries
Martha and the Muffins
Faye Wong
Sophie Zelmani
Joanna Newsom
Patti Smith
Gotta ask... what are you into? You say "Nice" music. You want polite parlor style, or are you open to anything?
If you like Patti Smith, you should be listening to some PJ Harvey and the Kills (Alison Mosshart is vocalist). Johnette Napolitano (Concrete Blonde, Pretty and Twisted).
Perhaps some Cowboy Junkies (Margo Timmins, vocalist).
Eleni Mandell, comes to mind.
You may like Cat Power. Devil Doll borders on a rockabilly vibe, and Imelda May too.
If you like the Cranberries, you may enjoy Shirley Manson in Garbage.
I'm very fond of Monique Ortiz (Bourbon Princess, AKACOD).
