Perfect blend

Renee Fleming, the hippest cat in opera, hosts "American Voices," a delightful mix of performances and discussions about various forms of music. Featured artists include Alison Krauss, Dianne Reeves, Sutton Foster and Eric Owens. Make sure you hang around for Sara Bareilles' killer version of "Goodbye Yellow Brick Road." 8 p.m. Friday, TPT, Ch. 2

Animal farm

"Incredible! The Story of Dr. Pol" provides the back story for one of cable's most popular veterinarians, although the word "incredible" is pushing it a bit. The European-born doctor's biography isn't really all that much more remarkable than tales from an endless stream of immigrants who discovered great opportunities in America. 9 p.m. Saturday, National Geographic Wild

Foreign legion

"The Golden Globe Awards" should have zero credibility with its limited number of anonymous voters. Yet somehow the event manages to be a star-studded event that eerily predicts Oscar nominations. It doesn't hurt that the show has once again recruited Tina Fey and Amy Poehler to host. 7 p.m. Sunday, KARE, Ch. 11

Where the tall corn grows

You would hope a little Midwest charm would make Hannah a sweeter person. But a stint at the Iowa Writers' Workshop in the new season of "Girls" does little to soothe her selfish ways. Look for all too brief cameos from Anthony Edwards and Ana Gasteyer as Shoshanna's all too attentive parents. 8 p.m. Sunday, HBO
