About Captain Ambivalent

Ambivalent – having or showing simultaneous and contradictory attitudes or feelings toward something or someone (Webster)

Captain Ambivalent (aka Dan Biemer, pronounced “BEE-mur”) is a nerd-rock singer/songwriter/superhero, boldly battling market forces since 2005. His glacial rise from obscurity to international obscurity began at the Front Porch Music open mic in Valparaiso Indiana and has grown to include Doctor Demento, The Midnight Special, South Bend Public Television, PierogiFest, GenCon, one-man shows in Fringe Festivals and alternative theaters, and even a brief cameo on America’s Got Talent. Learn more than you ever wanted to know about his musical back story in “How I Learned to Stop Worrying And Love The Accordion.”

The Captain is available for concerts, one-man shows, variety lineups, open mic hosting, media, and private parties.

Captain Ambivalent performs solo in the proud tradition of Weird Al YankovicThey Might Be GiantsJonathan Coulton, and Calvin and Hobbes, half of which are actually duos. With this discrepancy in mind, his debut album, “Fear The Accordion” (2012), enlisted long-time collaborator Mark Frey of the 1990s Buffalo NY band “Riley” to help create a signature accordion, drum, and tuba based sound they thought about calling “oom-punk” but found it was too hard to say. His genre-defying second album, “Pirate Ninja Zombie” (2014), added touches of mariachi, bluegrass, easy listening, prog rock, hip-hop, old-time country, gospel, house, and even musical theatre. But the main focus is always the words. The 50th anniversary of GenCon brought a 10 song EP of extra-geeky songs called “Save The Orcs” (2017). Click the images below for details.
