Ugly Casanova is an American indie rock band carried on Sub Pop Records. The band has released one album, Sharpen Your Teeth.
According to the Ugly Casanova website, in 1998 a man named Edgar E.Graham, a.k.a. "Ugly Casanova", impressed himself upon the band Modest Mouse while backstage at a concert in Denver, Colorado. After some prodding, he shared his work with the band and began performing it early before shows while some people were milling around.
