I'm reasonably sure nobody here will have heard of Kaye Brewster, but I really like her. Maybe you will too. Her website can be found at http://www.polopop.com/index.html and she has quite a few mp3 files available for your perusal.
Here is a quote from her 'about' page: "Let me introduce myself. I am Kaye Brewster, aka Kaye, aka Polopop. Why do I use two names? Because I'm swept by conflicting musical moods and it doesn't seem fair to subject the people who enjoy my dreamy soothing celtic sounds, to my demonically trivial experimental synthpop. (And vice-versa of course). So once you discover which me is you, you can relax and listen in sheer, uncontaminated pleasure."
I'm leaning more towards her "bubbly experimental scintillating synthpop" side, as I first heard her in a song with Linus Walleij in the very awesome Stygg Sylt, but after listening, I am really enjoying her "swirling celtic folk pop and soothing sleep-songs" too. Everything's free, as well, so why not give her a chance?
