Nick Drake and others like him

Have enjoyed getting to know Nick Drakes music...was wondering if there are others from the same era in the same vein that I should hear... this was before my time!
Nick always reminded me of a quieter version of Donovan, there's a few 'best of Donovan' discs around.

Another one would be Robert Wyatt 'Rock Bottom'. It got 5 stars in 33 reviews on Amazon:
Someone more recent - equally as unique who has unfortunately passed on as well - Chris Whitley. Perhaps 'Dirt Floor' might be a good start, however do yourself a favor and spend some time exploring his other offerings as well.
definitely Elliott Smith (S/T, either/or, XO). also try Bonnie 'Prince' Billy's 'Master and Everyone'. but in the end, Nick Drake remains unique...
