Jimmy Gilmer & The Fireballs – Sugar Shack (1963)

I imagine Tom Fogerty & John Fogerty of Creedence Clearwater Revival sitting around listening to this record and saying "We could do a cover of Susie Q". Surprising quality from the early 1960s with intricate guitar parts that sound completely out of time and space.
