A special KVMR 89.5 FM benefit showing this Sunday of the new film “Duck’s Breath Grand Finale” won’t have the fancy trimmings that usually accompany a movie premiere. “The price of red carpets has gone through the roof, and you just can’t find those huge spotlights around here at all,” quipped longtime Duck’s Breath manager Steve Baker, also the Program Director at KVMR. Two members also created the “Ask Dr. Science” series of “misinfotainment” that aired on over 200 public radio stations during a marathon 20-year-run. The new film concentrates on a rapid-fire series of Duck’s Breath short sketches. “So far, we’re one for three.”Oh, and it’s “minnows and garlic,” according to Kessler, whenever asked what Duck’s Breath smells like.
