The album was produced by Joe Wissert. Hip hop artist Ludacris has also named this LP as one of his five favorite records which he considers forerunners of hip-hop.[3][5]
Lester Bangs of Rolling Stone noted a "heavy Sly influence" and the "smooth harmonies" of The Fifth Dimension on the LP.[10]The Village Voices Robert Christgau was ambivalent towards the album's various musical "cross-references", including "the expert vocal harmonies [that] neither fit the concept nor assert any personality of their own", and said that even its successful songs have "a way of slipping away unnoticed once the record is over".[9]
Larry Ridley of DownBeat, with a 5 out of 5 rating, exclaimed "go
out and buy this record and keep your eyes and ears open to Earth. Wind and Fire."[14] Al Rudis of the Chicago Sun Times found "Earth, Wind and Fire brings to mind Bossa nova, Sly and the Family Stone, Ray Conniff, Afro-Cuban music and The 5th Dimension".[11]
John Bush of AllMusic gave the album four-and-a-half out of five stars and complimented the song's' "freewheeling arrangements". Bush found "the songwriting was as strong and focused as the musicianship" and praised the LP's social context, noting "unerringly positive compositions, reflecting the influence of the civil rights movement with nearly every song urging love, community, and knowledge as alternatives to the increasing hopelessness plaguing American society".[8] Bob Talbert of the Detroit Free Press also wrote "I'm not sure what to call this group. Afro-gospel-jazz-blues-rock? Must there be a label?".[12]
Isaac Hayes called Earth, Wind & Fire one of the band's five essential recordings.[15]
