Frankie Valli

Frankie Valli, born Francesco Castelluccio in Newark, New Jersey, is an American singer best known as the falsetto-voiced frontman of The Four Seasons, one of the defining vocal groups of the 1960s pop era. His distinctive high tenor and falsetto delivery became instantly recognizable across the group's run of hits, helping The Four Seasons stand alongside The Beach Boys and The Beatles as one of the era's biggest American vocal acts.

Alongside his work with the group, Valli built a substantial solo career, scoring major hits such as «Can't Take My Eyes Off You» and the title theme to the film «Grease», a chart-topping single that introduced him to a new generation of listeners in the late 1970s. His voice, warm yet piercing in its upper register, gave him a signature sound that translated easily between the group's harmony-driven pop and his own more orchestrated solo ballads. His decades-long career, spanning doo-wop-influenced beginnings through disco-era solo success, later inspired the jukebox musical and film «Jersey Boys», which dramatized the story of The Four Seasons and brought renewed attention to Valli's catalogue. He remains one of the most enduring vocalists of the American pop and rock era.
