These recordings from 1963 and 1964 predate his better known Verve albums and were not issued until after the success of those albums. The songs are in a more straight forward blues style than his later folk, rock and pop styles and are a mix of traditional songs, contemporary blues and his own songs including the driving Fast Freight and I Can't Slow Down.
In his review for Allmusic, music critic Richie Unterberger wrote "The material isn't nearly as distinctive as the best of Hardin's work, but the performances rank with Dave Van Ronk and Fred Neil as the best white blues/acoustic folk to emerge from the early-'60s Greenwich scene. It's still well worth tracking down."
