Time to ID another existing song that comedy nerds must be curious about (this time, it's the Portlandia theme)

Portlandia is the amusing and mostly improvised IFC sketch comedy show created by drummer-turned-SNL star Fred Armisen and former Sleater-Kinney frontwoman Carrie Brownstein and starring the duo as various characters in Brownstein's current hometown of Portland, Oregon, the tweeness capital of the world. The show returns this Friday for a second season full of more jabs at hipsters, more of Armisen and Brownstein's fellow musicians appearing in sketches a la first-season guest star Aimee Mann and more interesting-looking footage of Portland, where the show is filmed on location.

A gorgeously shot montage of the sights and real faces of Portland (none of those faces are Armisen's or Brownstein's during this part of the show), the Portlandia opening title sequence is one of TV's most evocative titles. That's not surprising--Portlandia is a Broadway Video joint, and Lorne Michaels' production company has a nasty habit of giving its sketch shows (from SNL to Kids in the Hall) the most stylish shot-in-the-streets opening titles. But what's that hypnotic tune during the Portlandia titles?

The Portlandia theme that viewers have been pestering IFC about since the show's first season is the 2009 track "Feel It All Around" by chillwave genre pioneer Washed Out, a.k.a. Ernest Greene.
