this thread certainly brings back the memories! i was a freshman in college and was walking across campus when i heard this absolutely clear beautiful voice coming out of a window and i just stopped and was knocked flat! i stopped at the room and found out that it was JB singing Long Black Veil. I wore out that record the next 2 years; I'm afraid my roommates didn't like her as much as I did. Their tastes ran to the Beachboys.
   
also 'discovered' judy collins shortly thereafter. if you are looking for a comparable voice nowadays, check out Priscilla Herdman!
