LOS ANGELES — Ask Fred Armisen and Carrie Brownstein to give up hints about the new season of “Portlandia,” and a few words suffice to make any true admirer of the IFC satire giddy with anticipation.

“I would say raw milk plays heavily,” said Armisen. “I would say the world of modeling, which we never really got into. Health care, a whole episode on that. And Fourth of July – what is that like in Portlandia?”

That’s medical care in general, not Obamacare in particular, Armisen said, and the reference to a full episode is an important one for season five, which begins at 10 p.m. Thursday.

After four years of knitting half-hours out of varied sketches with recurring characters, the IFC comedy is going deeper into the lives of those characters and their semimythical city. Most of the 10 half-hour episodes will focus on a single story, Brownstein said.

“When I watched the cut of the premiere episode, it really felt like a different show,” said the musician-writer-actress.

Former “Saturday Night Live” cast member and musician Armisen agreed, comparing the approach to creating “extended plays.”
