Anton Armstrong, director of the St. Olaf Choir

The 75-voice St. Olaf Choir from Northfield, Minnesota-among the finest in the world-celebrates its 100th anniversary this season. Directed by University of Illinois alumnus Anton Armstrong, the choir will come to the Krannert Center in Urbana on Thursday. I'll spend the hour with Dr. Armstrong on the Monday edition of "Live and Local." NOTE: Due to technical difficulties, this interview did not air completely on the live broadcast. The sound file here is my complete interview with Dr. Armstrong as it was intended to have aired.
