When this material originally resurfaced in an earlier Rhino-celebrates-the-"70s program, many rock scribes contorted themselves into revisionist pretzels: this isn"t so bad, they argued--none too convincingly. There"ll be none of that here: much of the music on this colossal box set is godawful. The world doesn"t miss the likes of Sammy ("Chevy Van") Johns and Sammy ("Candy Man") Davis. Or at least it doesn"t miss the records they cut during the decade of disaster flicks and Jonathan Livingston Seagull. That said, this elaborate box is something to behold. The lovingly compiled 92-page booklet provides background on the ridiculous (David Soul, C.W. McCall, Carl Douglas) and the sublime (Parliament, James Brown, the Staple Singers), and the music swings on the same pendulum, with Harry Chapin, Bill Withers, and Cat Stevens sitting amid Wayne Newton, The Captain & Tennille, and Meco"s jittery electro-take on the Star Wars theme. Seven discs, 160 selections! To paraphrase a popular ad slogan of the era, you won"t believe you listened to the whole thing. --Steven Stolder
