The Four Seasons (since 1967, known off and on as Frankie Valli and The Four Seasons--although not shown that way on any of their hit records), is an American pop and rock group. They also had a sound somewhat reminiscent of doo-wop, although they were not thought of as a doo-wop quartet. By the mid 1960s, The Four Seasons had become an internationally famous rock-and-roll group. The Vocal Group Hall of Fame has stated that it was the most popular white rock band before The Beatles.
