Scott.Jennifer Higdon's Violin Concerto unfolds as a slow burn with flickering, firefly-like tones, then straps you into a sonic roller coaster, corkscrewing through ever-changing musical images. When you have experienced the sublime disorderliness of Higdon's concerto, it seems miraculous that it ultimately makes sense; you have experienced something that was perceivable if not completely comprehensible.

The winner of the 2010 Pulitzer Prize for Music, Higdon's concerto could be bewildering for audiences at the Quad City Symphony's December 7 and 8 concerts, with its copious, fast-changing variations of instrumental combinations and dynamics: violin harmonics with small finger cymbals, tingling high woodwinds with low, growling cellos and basses, sudden changes in volume, and constantly contrasting textures of sound. The musical events might seem random at first, but somewhere in your brain, you should be able to recognize and reorganize them enough to get a sense of Higdon's complex yet stunningly accessible musical thinking.
