The Minnesota Orchestra had assembled on the stage three Fridays ago, and the air inside Orchestra Hall was filled with that recognizable hum of tuning and last-minute rehearsing.
Upstairs, in a soundproof studio no larger than a walk-in closet, Melissa Ousley was oiling her vocal cords and warming up as host of Minnesota Public Radio's live Friday night broadcast.
"Do you have your cellphone off?" asked engineer Michael Osborne.
"I do, and I have thrown out my chewing gum," Ousley responded as the seconds ticked toward the moment when she would introduce guest conductor Nathalie Stutzmann and the orchestra would launch into Prokofiev's Symphony No. 1.
MPR is celebrating its 50th anniversary this year and on Nov. 11, the orchestra will play a special concert to mark an association with the public broadcaster that dates to 1971, when host Arthur Hoehn introduced conductor Stanislaw Skrowaczewski and the orchestra at O'Shaughnessy Auditorium in St. Paul.
Since then, nearly 1,200 concerts have been aired to listeners who can't make it to Orchestra Hall, or who — like baseball fans listening to the play-by-play — enjoy sitting at home in an easy chair with the stereo speakers in the background.
This Friday, Brian Newhouse, MPR's managing director for classical programming, returns to his regular job as host. But on Nov. 11 he will take a seat on stage as emcee and introduce pieces he helped select with music director Osmo Vänskä, while American Public Media's Fred Child fills in as the on-air voice.
"I get feedback along three themes," said Newhouse, when asked why MPR continues to do these live broadcasts. "First is the person from Warroad, who says they'll never be able to get to downtown Minneapolis. Second is the listener who says they attend the concert on Saturday night but love to hear the interviews with artists and the inside information they pick up on the Friday broadcast.
