portishead, goldfrapp, looking for more ......

Sneaker Pimps- Becoming X, it is a must have classic.
DollsHead- Frozen Charlotte, accuratly fits your discribtion

This one is take it or leave it, you'll either think this girl has the sexiest voice in the world or you'll hate, eiter way the 'music'(if you can even call it that) in the this one very special track is amuzing if nothing else. Her it goes:
Danny Tenaglia- Global Underground, Athens-004, disk one track 12 the song "Frank Sinatra" featuring Miss Kitten, if you have a chance to pick up this disk listen to that track and tell me what you think. Personally I love this girls voice, don't know why, but it is inspiring. Don't play it the first time with wife/girlfriend or the kids around, when you hear it you'll understand!

If you don't mind french(always sexy!) than go for Guesch Patti -- Blonde album and have your mind blown.

UMMMMMMM.....Marakantz, just my mind?????? I may have been interested if it was not so limiting!!! LOL

I listen to everything listed above, but my chill out faves are St. Etienne (their entire playlist), Morcheeba, and Ivy. I find that Paul Van Dyk has many songs that stir me with female vocalists, especially on the CD, "Out there and back".

I especially appreciate this music when I am in logic 7 etc on the Lexicon.

Laurie Anderson -- "Strange Angels"
