I'd like to add Eddi Reader to this list. I think you would enjoy her cd 'Angels and Electricity'. Martha Sebastyen, a hungarian singer, is a joy to listen to as well. Especially her traditional material with Muszikas. And there is a Portuguese band called Madredeus, with Teresa Salgueiro, who has an angelic voice accompanied by cello, accordeon, and guitars; and you would be touched by a Spanish lady called Marina Rossell; my father heard her on the radio about a year ago and wrote her name on the back of a matchstick box (as you do). We now both have her cd called Ha Llovido in our collection. I recommend it especially if you like a clear, more mature voice. Enjoy!
