Robert Leroy Mothersbaugh Jr. (/ˈmʌðərzbɔː/; born August 11, 1952), also known by his stage name Bob 1, is an American musician, singer, songwriter and composer.

In early 1970, Bob Lewis and Gerald Casale formed the idea of the "devolution" of the human race after Casale's friend Jeffrey Miller was killed by Ohio National Guardsmen firing on a student demonstration.

[7][8] Following the commercial failure of their sixth studio album Shout, Warner Bros. dropped Devo.

Their first project was a soundtrack for the flop horror film Slaughterhouse Rock, starring Toni Basil, and they released the albums Total Devo (1988) and Smooth Noodle Maps (1990), on Enigma.

The lyrics of some of the songs were changed for family-friendly airplay, which has been claimed by the band to be a play on irony of the messages of their classic hits.

In 1989, Bob Mothersbaugh and other members of Devo were involved in the project Visiting Kids, releasing a self-titled EP on the New Rose label in 1990.

Visiting Kids appeared on the soundtrack to the film Rockula, as well as on the Late Show with David Letterman.
