Alexis "Lex" Marshall is the vocalist for the American noise rock band Daughters and formerly of As the Sun Sets.[1] In As the Sun Sets, his vocals were a mixture of high pitched screaming and death growls, but he has since abandoned both, as he uses a clean vocal style in Daughters. In 2012 he formed Fucking Invincible with a current member of Dropdead and Soul Control.

Marshall was originally from Providence, Rhode Island, but currently lives in Pennsylvania.
