Spring (American Spring album)  Spring (known outside the United States and in subsequent reissues as American Spring) is the first and only album by American pop duo American Spring (then known as "Spring") released in July 1972. Largely ignored at the time of its release, it has now come to be seen as a valuable collector's item due to Brian Wilson of The Beach Boys' participation. "Spring" was largely tracked in Brian Wilson's home studio in Bel Air, California from October 8, 1971 to May 1972, engineered by Stephen Desper. The track for "Good Time" was sourced from an outtake from the Beach Boys' album "Sunflower" and was recorded on January 7, 1970. Stephen Desper and David Sandler oversaw the recording of the majority of proceedings. Statements by Desper have estimated Brian's contributions at around 5%, but Desper added "5% of Brian Wilson is equal to 100% of anyone else" noting that whenever Brian did work, it would be a substantial contribution due to his proficiency in the studio. Marilyn Wilson of American Spring and former wife of Brian Wilson disagreed with Desper somewhat, recounting Brian produced "about a quarter" of the album, a statement that Diane Rovell agreed with. It has been hypothesized that Wilson's contributions to the 1972 Beach Boys album, "Carl and the Passions – "So Tough"" were minimal as the sessions coincided with the recording and promotion of this album. Reviewing in "" (1981), Robert Christgau wrote of the album: "In which Brian Wilson produces his old female backup group—the Honeys, featuring his wife Marilyn—in what sounds like the best and is certainly the most charming Beach Boys album since "Sunflower". The old combination of ingenuousness and sophistication works as well as ever, only this time the vocals rather than the lyrics are naive—direct, pretty, effortless, thoughtless. And Wilson's studio work is as precise and humorous as ever." American Spring  Additional personnel
