What I exactly mean by progressive/psychedelic/acid-folk is rather unclear and the referential range is rather big.
Applying non-music attributes, such as 'year', 'country', 'record-label', 'producer' etc. normally narrows it down a bit and I normally use the term to refer to folk-music produced in england/scotland/ireland in the years 1966 (isb's debut) to 197? (let's just say 1975 for convenience sake).
Of the three parts in the label "progressive/psychedelic/acid" I can say the following:
Progressive (here) means that the music has to be non-mainstream (not likely to be played on national radio)
Psychedelic has to do with drugs or a 'druggy-sound'. (Isb sounds very druggy fairport convention doesn't*)
Acid has to do with an 'beyond-category-out-there-weirdness' that is usually also druggy but a bit more than that.
These are not necessary and sufficient conditions for the lists that you want to post. Just vague guidelines.. I hope you see where I'm going.. The only strict rules are: the British iles, years 1966-75, folk of some strange sort (this means that jethro tull is also included). And not too many albums by same bands plz. Looking forward to see some lists..
By the way - runner ups for my list:
vashti bunyan - just another diamod day (1970) (bordeline case)
fresh maggots - s/t (1971) (that's fuzzy)
farport convention - liege and lief (1969) (another borderline case)
*fairport's debut with judy dyble is quite psychedelic, I admit - but in their prime they toned that aspect down a bit.
