Turn up the Duffstep and turn that frown right-side up, because we’re heading in the Aca-Upside-Down! This week, we’re crossing over musical comedy Pitch Perfect and ‘80′s throwback sci-fi tv show Stranger Things. Join us for a conversation about Steve’s a cappella audition song, the limits of nostalgia, actual human a cappella concerts that are definitely not aliens luring humans into a false sense of security, and the true purpose of rickrolling. We will decide who is the Duff, the Duffer, and the Duffest!
