Nick Drake and others like him

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...

Lvk47, Im pretty sure Tim Buckley drowned, not suicide.

Wrong again. According to Wikipedia he O'D on heroin.

Jeez, I'm an ass. Jeff did drown, the old man (Tim) O'd.
