William Roy "wiL" Francis (born January 8, 1982 in Seattle, Washington) is an American rock musician, record producer and author. He came to prominence as the lead vocalist and principal songwriter of the post-hardcore band Aiden. He has also released four solo albums under the name William Control, featuring a synthesizer driven darkwave style. Francis also acts as producer to the bands A Midnight Tragedy and Ashestoangels. Francis joined the original lineup of Aiden in 2003 as their bassist and replaced Steve Clemens as lead vocalist later that year. Since then, he has been the creative leader behind Aiden and, as of 2015, is the only member of the original lineup still in the band. During Aiden's hiatus from 2012 to 2015, Francis' primary musical output was William Control. In addition to making his own music, Francis has produced albums for A Midnight Tragedy, Ashes to Angels, and Fearless Vampire Killers. He has released two books of poetry and two novels. In May 2009, Kerrang! called Francis "one of the most enigmatic and talismanic frontmen in rock music today."
