Recorded on January 13, 1973, Rainbow Concert marked Eric Clapton's return to the stage for the first time since The Concert for Bangladesh in August 1971. Joined by a band that included Pete Townshend, Ron Wood, Steve Winwood, Jim Capaldi, and Rick Grech, Clapton performed with an incredible amount of inspiration right from the opening notes of Layla, which is included here for the first time.  In fact, considering that the original rendition of this album consisted of a mere six tracks, much of this collection is new.  As such, it's one of those worthwhile reissues that actually adds significantly to an original work.  The show's set list provided quite a retrospective of Clapton's career, and songs from his days with Cream, Derek and the Dominoes, and Blind Faith, as well as from his early solo outings, magically flew from his fingertips.  Indeed, it's a star-studded affair that marked the guitar legend's long overdue return to the spotlight.  ½
