“This is fun for you guys, right?’’ When Carrie Brownstein asked the Berklee audience that question toward the end of Monday’s road-tour version of “Portlandia,’’ her charmingly loose sketch-comedy television show with Fred Armisen, she intended it as a self-deprecating joke about the five-piece band taking its time deliberating about what to play next. Intentionally or not, though, she wasn’t really joking. The meandering back-and-forth not only didn’t grind the show to a halt, it was precisely what the audience came to see in the first place.
Not that it was entirely clear beforehand what the performance would entail, exactly. What it wasn’t was the TV show transplanted to the stage. There were video clips from upcoming episodes. There were songs. There was an audience Q&A. There was even cake. More than anything, there was the rambling, easy-going rapport of Armisen and Brownstein, casual and confident like they were sharing funny, odd jokes with longtime pals.
