It's not the first time Marin Alsop and ensemble have received ASCAP accolades for being different, but in a time when the magnificent Maestra's days in Denver seem numbered as a result of her fire and enthusiasm, it's especially worthy of note, concrete evidence of what everyone's been saying all along: Marin Alsop doesn't settle for sap, though she's willing to allow more popular programming within the confines of a CSO season. But you can also count on her to sprinkle the concert lineup with more difficult and challenging works, meaning you're likely to hear Mahler along with your Rachmaninoff, or a world premiere of Bresnick's Double Percussion Concerto along with the crowd-charmer Pictures at an Exhibition.
