The Pentangle

I recently watched The Ballad of Tam Lin, very odd verging-on-folk horror movie that they did the soundtrack for, worth a watch imo!

I'm going to have to check that out.

Yes, their records are still pretty cheap — sometimes very cheap if you look hard enough. You should be able to get at the very least Cruel Sister for $5 or less. The other ones for $10-20 generally.
