The 2020 eight-CD box set essentially represents a complete telling of 's second act: the transition from blues outfit to conquering pop stars. Every one of the studio albums released between 1969's and 1974's are here, each buttressed with bonus tracks. Most of these bonus tracks are non-LP singles or single edits: has both parts of "Oh Well" along with "The Green Manalishi (With the Two Prong Crown)," has both-sides "Dragonfly" and "Jewel Eyed Judy," etc. The only unreleased track among these is "Good Things (Come to Those Who Wait)," which is added to , but the box also features a full previously unreleased live-in-the-studio concert, Live at the Record Plant, Sausalito, CA 12/15/74, which was given just prior to and joining the band. The concert is first-rate and the bonuses are strong, but the main attraction of the set is getting this entire chapter of 's history in an affordable fashion. ~ Stephen Thomas Erlewine
