The Kingston Trio made the urban folk revival a commercial commodity in the late '50s with the radio success of reconfigured folk songs like their smoothed-out version of the Appalachian murder ballad “Tom Dooley,” and the group’s clean-cut collegiate image gave them appeal across the board. They were also easy and inexpensive to record, and released four albums in 1958 and 1959, all of which are represented in this two-disc, 40-track set, which makes it a nice introduction to the trio’s early years.
