Extreme Measures is the first project in clarinetist Jean Kopperud’s Rated X series. It is seven clarinet and piano works written for Kopperud asking composers to dare to stretch the medium. The Winnipeg Free Press reviewed a past project that Kopperud toured, which might best describe Rated X. “You can expect to have your head bent a little. You will stay awake. You will be fascinated and infuriated . . . and exhilarated by what you have heard.” Rated X (“Extreme Measures”) premiered in the fall of 2008 on the West Coast and was recorded in the spring of 2009. A graduate of Juilliard and former student of Nadia Boulanger, Kopperud has toured the U.S., Canada, Europe, Japan, China, the Caribbean and Australia as a concert soloist and chamber musician. She performs with the New York New Music Ensemble and is a professor of music at the University of Buffalo.
