"This four-disc set provides an in-depth survey of the breadth of Vanguard's catalog, and also serves as a sort of musical journey through the cultural shifts and changes of the '60s. The '70s weren't as kind to Vanguard as the '60s were, and the label was sold to the Welk Music Group in 1985, undergoing a kind of resurgence with albums from John Fogerty, Greg Laswell, Merle Haggard, Chris Isaak, Linda Ronstadt, Robert Cray' and others, but Vanguard's '60s catalog continues to be the label's defining jewel. This set shows why".
