The free publicity, complete with an online post by Donald Trump, spurred a surge in record sales. I recently spent two days with Gangstagrass, a band that is making music that actually unites us, and reflecting on why it isn’t better known. A version of the group produced the theme song of the TV drama “Justified.” (The song, “Long Hard Times to Come,” was nominated for an Emmy in 2010.) The multiracial band was created by Rench, a Brooklyn-based musician and producer. When he isn’t making music, Mr. Whitener is a stay-at-home dad.
