Ugly Casanova is an American band on Sub Pop Records. The band has only released one album: Sharpen Your Teeth. The band is a side project of Modest Mouse singer, Isaac Brock and Holopaw member, John Orth; initially, however, the band's origins were a mystery. The legend of Ugly Casanova was based around the character of Edgar Graham, a.k.a. "Ugly Casanova", who (according to the Ugly Casanova press release) met 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.
