Welcome to MB, Calluna!
Your Dead, Drake, and Dylan albums are great favourites of mine too! Here are a couple of recs you might like because they are equally, consistently good and from the same era:-
Blue - Joni Mitchell
An Evening With - Dando Shaft
Dust Bowl Ballads* - Woody Guthrie
Whales And Nightingales - Judy Collins
Basket of Light - Pentangle
* This one was recorded in 1940, on 78 r.p.m! Re-issued in 1964 I think
