This Grammy winner now collaborates with many musicians in myriad styles and leads acoustic quintet Punch Brothers. Thile's solo albums include Bach: Sonatas and Partitas, Vol. 1 (Nonesuch).

One minute he's mild-mannered Tim Russell; the next he's George Bush or Julia Child or Barack Obama. We've yet to stump this man of many voices. Says fellow APHC actor Sue Scott, "He does a better Ira Glass than Ira Glass." A well-known Twin Cities radio personality and voice actor, Tim appeared in the Robert Altman film A Prairie Home Companion and the Coen brothers' A Serious Man. Tim has also been reviewing films professionally for over 10 years.

On APHC, Sue Scott plays everything from ditzy teenagers to Guy Noir stunners to leathery crones who've smoked one pack of Camel straights too many. The Tucson, Arizona, native is well known for her extensive commercial and voice-over work on radio and television, as well as stage and movie roles, including the part of "Donna" in Robert Altman's A Prairie Home Companion.

Sound effects man Fred Newman is an actor, writer, musician, and sound designer for film and TV. Turns out, no one is more surprised than Fred that he's made a career out of doing what he used to do behind the teacher's back -crossing his eyes, making sounds, and doing voices. He readily admits that, growing up, he was unceremoniously removed from several classrooms, "once by my bottom lip."
