(2-LP set) The fourth volume of the Anthology was never finished by Harry Smith. He managed to choose and sequence the tracks but never submitted liner notes to Folkways. Revenant Records released a version of this volume in the late 1990's with excellent liner notes and packaging. For our current release we have decided to not include any liner notes and conform the packaging to the same style as the first 3 volumes. This volume explores rhythmic changes that occurred in folk music between the late 1920's and early 1940's.
