The Folk Voice is a Revival 2 thing; before that you had the likes of Jack Langstaff essaying the sort of repertoir the Watersons would later cover in fine old style. Then you had the likes of Mike Waterson, Ewan MacColl and Peter Bellamy taking the human voice where it had never gone before, but Traditional Song was always best served by idiosyncratic stylists - Davie Stewart, Willie Scott, Phil Tanner, Harry Cox et al. So, to thine own chops be true, though things seem to be levelling out of late. This isn't unique to Folk though - where's the 2011 equivalent to Captain Beefheart? I'm sure he's out there somewhere, just these days we're less likely to hear of him.
