Echo Nest has a new demo where you can pick a genre, see the "hotttest" artist for that genre, and then play those selections via rdio. The classical genre is boring; drone (as follows) less so, even if you don't normally associate these artists with drone.
This reminds me of the somewhat diverse set of artists on the Roots of Drone collection. Anyway, the Echonest "hotttest" drone artists:
- Mountains
- Om
- Swans
- Electric Wizard
- Sleep
- Neurosis
- Grouper
- Iannis Xenakis
- Benoit Pioulard
- Stars of the Lid
