The signature sound of RCA production gurus Hugo Peretti and Luigi Creatore is best likened to fondue -- rich, creamy and irrefutably cheesy. Let's Fall in Love, credited with poetry and panache to the "Cascading Voices of the Hugo & Luigi Chorus", updates the signature sound of Eisenhower-era pop chorus albums for Kennedy's New Frontier, adding energy and even a touch of soul to the lush, ludicrously romantic formula. It's fluff, of course, but undeniably well-crafted fluff, fully exploiting the cutting-edge of early-'60s studio technology to forge a multi-dimensional sound that's as big as it is bold.
