Centennial Horizon Centennial Horizon was commissioned by Albany trumpeter Catherine Sheridan. With two contrasting movements (Aspen Grove and Roaring Gunnison) connected by an interlude (Alpenglow), I have attempted to capture some of the beauty and adventure of what truly is an amazing place: Colorado (the "Centennial State"). Inspired by my late grandmothers love of that state, the first movement is an homage to her.
