William Roy "wiL" Francis is an American rock musician, record producer, author, and artist. He came to prominence as the lead vocalist and principal songwriter of the horror punk band Aiden.

William Control is an American music project founded in 2008 in Seattle, Washington. It was the side project of Aiden's William Francis before Aiden's hiatus, and he later operated as William Control full-time. 'William Control' therefore refers to both the band as a whole and to Francis as his stage name. Francis was signed to Victory Records before starting his own independent label, Control Records, and, as William Control, has released five full-length albums, an EP, two acoustic albums, two live DVDs and a remix album (Remix). The first part of Revelations, The Pale, was released on October 14, 2016. The second EP The Black followed on February 17, 2017, and the third, entitled The Red, followed that with a release date of July 14 of the same year. The album was completed by The White on November 24.
