One of my favorite albums in the world is by Ulla Pirttijärvi, the artist profiled here.

The CD is "Ruossa Eanan / Russian Land (1998). Warner / Atrium 0630-19717-2."

Hard to describe, but joik with gentle folk/new age ambient sounds. Very contemplative and serene. I got it back when it came out (gulp, ten years ago!) and still listen to it regularly. Highly recommended, if you come across it!
