Castle Creek was written by Dan Welcher in celebration of the Aspen Music Festival's 40th anniversary, and served as a special tribute to the Festival's longtime President, Gordon Hardy. "Castle Creek" itself is a tributary of the Roaring Fork River on which the Aspen Music Festival campus (as well as Hardy's home) is built. Gordon's initials (G.A.H.) are used as the musical basis for the fanfare, which is centered on the ascending pitches G, A and B, and reflects the upward motion and positivity of the Aspen Music Festival itself. For advanced players.
