“Thunder Road” by Bruce Springsteen (1975)
It’s hard to imagine the Boss’ small town New Jersey saga without the E Street Band backing him up, but stripped down to a voice and guitar it takes on the appearance of a story-telling folk ode. The tune went through many incarnations before showing up on the grooves of Born To Run, and this early version was originally titled “Wings For Wheels”.
“Gypsy” by Fleetwood Mac (1982)
The etherial beauty of Stevie Nicks‘ melancholic masterpiece is somehow intensified with just her vocals backed by an echo-drenched electric piano. Sure, it’s not technically “acoustic”, but it’s still pretty awesome.
