A Westward Expedition is a musical tribute to commemorate the 200th anniversary of the Louis and Clark expedition and its mission to explore the uncharted West. After a powerful introduction, the main theme is introduced in a spirited Allegro section, portraying the excitement as the Corps of Discovery set out on its westward journey. This is followed by the lush and beautiful Andante section, which depicts the thousands of miles of spectacular mountains, rivers and wildlife encountered along the route. The anticipation and thrill of reaching the Pacific Ocean (upon arriving at what is now the state of Oregon) is brought to life with a recapitulation of the opening theme, bringing the historic journey to an exciting end.
