Next from 1970 is In the Garden of Jane Delawney by Trees
I discovered Trees a few years ago, when I was looking for more albums that sounded like Liege & Leif and Basket Of Light (which would both be on my 1970 list except they came out in 1969) and my fried Tim asked if I'd heard of Trees.
After that, I downloaded both of their albums (both ca-1970) from here , and found that I liked this first one Garden Of Jane Delawney better than the second one On The Shore, which seems to be a contrary opinion on the internet.
Actually, there isn't a lot of Trees info on the net. Their AMG site consists of a snarky bio and by R. Unterberger and their wikipedia site is pretty sparse as well.
In fairness, most Trees songs aren't that noteworthy, singer Celia Humphris is no match Sandy Denny or Jaqui McShee or Maddy Prior, and guitarist Bias Boshell is no Richard Thompson or Bert Jansch, so they're kind of a poor man's Fairport Convention. But if you like Fairport and Pentangle and Steeleye Span, you'll probably also like Trees.
Here's their "Matty Musgrave" song, "Lady Margaret".
