Tune in to CBS Sunday night as the 57th Annual Grammy Awards are broadcast live from the Staples Center in Los Angeles. The Black Keys, Nickel Creek, Chris Thile & Edgar Meyer, John Adams, and Brad Mehldau are nominated for a total of 11 nominations.

Chris Thile, whose work is up for five Grammy Awards—two for A Dotted Line with his fellow Nickel Creek band mates Sara Watkins and Sean Watkins and three for Bass & Mandolin, his duo record with bassist Edgar Meyer—steps up to a mic of a different sort this weekend as he guests hosts A Prairie Home Companion for Garrison Keillor at The Fitzgerald Theater in St. Paul, Minnesota, on Saturday. Thile welcomes a very special band as musical special guests: Punch Brothers. He and his band mates celebrate the recent release of their album The Phosphorescent Blues. (Thile returns to guest host a Valentine's Day edition of the show the following weekend with another special musical guest: label mate Rhiannon Giddens, whose solo debut album, Tomorrow Is My Turn, is out next week.) Fans around the world can watch it all streaming online at prairiehome.org.

Thile spoke with Minnesota Public Radio's The Current early today about the rare honor of Keillor's asking him to guest host the show (Sara Watkins was the last to do so) and what to expect from the show this weekend. You can listen to the interview at thecurrent.org. And tune in to BBC Radio Scotland tonight at 8 PM to hear Punch Brothers on Another Country with Ricky Ross, recorded during their recent UK tour.

And tune in to CBS This Morning Saturday for a performance by Chris Thile and Edgar Meyer from their Grammy-nominated album Bass & Mandolin.
