Incredible String Band - Liquid Acrobat As regards The Air.
The I.S.B. go a bit electric on this and it's a late album (1971) but better than it's given credit for and it has that crisp Sound Techniques studio sound which seems to work for Folk Rock of this vintage.
"Talking of the End" and "Dear old Battlefield" are the good ones on this.
I think I picked this copy up as a teenager on a long since vanished second hand vinyl shop in Folkestone near the bus station.
Folkestone in the late 80's you could find all sorts of fun stuff.
