A Fever You Can't Sweat Out is the debut studio album by the American rock band Panic! at the Disco. Produced by Matt Squire, the album was released on September 27, 2005, on Decaydance and Fueled by Ramen. The group formed in Las Vegas in 2004 and began posting demos online, which caught the attention of Fall Out Boy bassist Pete Wentz. Wentz signed the group to his own imprint label, Decaydance, without having ever performed live.
