"Brontosaurus" is the third and final album by Da Vinci's Notebook, released on April 1, 2002. In 2001, the song "Enormous Penis" was released as the group's first and only single. Around this time, interest in the band spiked as they began to get played on the syndicated Bob and Tom radio show; their appearances on the show led to high demand for the single. Signature songs played on the show included "Ally McBeal", "Enormous Penis", "Liposuction", and "Title of the Song", with "Enormous Penis" remaining Da Vinci's Notebook's most popular song. "Brontosaurus" was released the following year. It was produced by Richard Greene, who had previously produced "The Life and Times of Mike Fanning". Guest appearances include Eddie Hartness and Robbie Schaefer of Eddie from Ohio, Valerie Vigoda from GrooveLily, and a cappella singer-songwriter Sean Altman. The newfound popularity brought by the Bob and Tom Show would bring more critics and fans to the album, with the album releasing to positive reviews. The album was the band's final release before disbanding in 2004. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
