Listen to Alison Krauss on iHeartRadio

Alison Krauss is marking a milestone.  She's celebrating her 20th anniversary as a member of the Grand Ole Opry.  The singer will celebrate the occasion with a special Wednesday night Opry show.  Union Station will be joining Alison for tonight's show, while Jamey Johnson, John Conlee, Kristen Kelly, and Mandy Barnett are some of the other artists slated to perform. 

Alison's 20th anniversary event is part of the Opry's "All American All-Star Week," which continues with special events and performances through Saturday.  There will be free music, food, and fun activities on the Opry Plaza, including a dunk tank fundraiser for the American Red Cross. 

And big names are turning out for this weekend's concerts.  The Band Perry will be taking the Opry stage for both of Friday's shows, while Jimmy Wayne, Eric Paslay, and Lennon and Maisy - from TV's "Nashville" - are just some of the performers on board for Saturday.  Carrie Underwood will play both shows both nights.
