John Darnielle has been all over (Fallon, Fork.tv, NPR, YouTube) promoting the latest Mountain Goats album, Life of the World to Come. This time, they do “Isaiah 45:23” on IFC’s “Dinner with the Band,” a show who’s premise is completely indecipherable from these clips online. I see the band, but where’s the dinner? I guess that might be a dining room, but there’s no dining room table, just some hungry guests like the gal with the half-shirt and the haircut (she’s into it though!).
