Few artists have such a singular voice as Franki Valli. His voice - an extraordinarily powerful lead falsetto challenged (and changed) the standing idea of what rock and popular music could sound like.

With his band The Four Seasons, Valli set the soundtrack to the 1960s and 70s. Today, new audiences still discover and devour his music. Though it’s been six decades since Valli arrived on the scene, there still hasn’t been another voice quite like his.
