This two-LP compilation was a crucial factor in the development of Clapton's solo status at a time when the artist himself was incapacitated by drug problems. Covering the years 1964 to 1970, History was a revelation, weaving together tracks from Clapton's various bands — the Yardbirds, John Mayall's Bluesbreakers, Cream, Blind Faith, Delaney & Bonnie & Friends, and Derek and the Dominos. Today, with its essential tracks, rarities, and previously unreleased studio jam on "Tell The Truth," plus liner notes, History looks like the prototype for the box set retrospectives of the '80s and '90s. In 1972, it defined Eric Clapton and helped save his career. And it still doesn't make a bad summation of his best work.
