Inventive Devo guitarist Bob Mothersbaugh belongs to one of the band’s two sets of brothers and one set of Bobs. His older brother is Mark Mothersbaugh, and he was Bob 1 to the late Bob Casale’s Bob 2, Gerald Casale’s younger brother. Although Devo became known for synths, its debut was a piledriving guitar album with Bob 1’s playing up front. Bob 1 also sang the “Secret Agent Man” cover, co-wrote key early songs and contributed memorable guitar parts even as sequencers took over. How did that feel? What was David Bowie’s involvement with Devo? What dark impact did the success of “Whip It” have on Bob 1? Have Mark Mothersbaugh and Gerald Casale, who complained about his band co-founder on his earlier Caropop appearance, made peace? Does Devo still have a future?
