William Alexander Chilton (December 28, 1950 – March 17, 2010) was an American singer-songwriter, guitarist, and record producer best known as the lead singer of the Box Tops and Big Star. Chilton's early commercial success in the 1960s as a teen vocalist for the Box Tops was never repeated in later years with Big Star and in his subsequent indie music solo career on small labels, but he drew an intense following among indie and alternative rock musicians. He is frequently cited as a seminal influence by influential rock artists and bands, some of whose testimonials appeared in the 2012 documentary Big Star: Nothing Can Hurt Me.
