With abundant sleevenotes by The Yardbirds’original manager Giorgio Gomelsky and Pete Frame’s family tree, this four-disc set documents the group’s progress from 1963 to 1967 in unprecedented detail. Beginning with the complete Crawdaddy recordings with and without Sonny Boy Williamson, the set presents early demos, the Marquee sessions (aka Five Live Yardbirds), and numerous alternative takes and half-finished tracks from the band’s period as a hit singles unit. Anyone interested in The Yardbirds will want this.
