In 1983, The Bobs put out their first self-titled album. This record earned the group a Grammy nomination and pretty much re-wrote all the rules for vocal group music. “Instrumental” arrangements, dissonance, vocal percussion, ringing harmonics and melodic solo voices all linked with quirkily comedic material—these are the trademark sound of The Bobs—a sound and style that has since been emulated by a cappella groups around the planet. Now, after 30 years of recording and touring, The Bobs finally take an overdue item off their “bucket list”—the “concept album.” Richard Bob, Dan Bob, Angie Bob and Matthew Bob are releasing in September an album of songs about famous (and not-quite-so famous) historical figures. The album title is “Biographies.” All the songs share a unifying theme—in some way, shape or form each song tells the life story of (or at least an event in the life of) some notables throughout history—also some obscure persons who will become notables after the record comes out.
