The undoubtedly best Earth, Wind & Fire-disk, for all that are in Groove and etc. not think of the comercial hits like "Let's Groove" as much. Absolutely unkomerziell! A live recording with everything your heart desires: long solos, groovy parts, driving bass, blower and so on. There are actually not many plates in the world who leave such. Actually, Earth, Wind & Fire for "Gratitude" should have put an end to. Because have better and you will never get it.
