The four tracks on this release have never been released on CD before! The fans of The Black Keys will not be disappointed. "The Moan" is the original studio version that appears on the Alive 7"; "Have Love Will Travel" is the B-side (which is a great rendition of this classic; a different version later appeared on "Thickfreakness"). "Heavy Soul" is a brilliant alternate version included on the vinyl of "The Big Come Up," and their cover of the STOOGES classic "No Fun" (also from the vinyl "The Big Come Up") is simply one of the very best covers you'll hear.
