Pianist Joel Sachs performs masterworks by Charles Ives, one of America’s greatest composers and one of the greatest modernists of the early 20th century. His rarely heard Piano Sonata No. 1 will be preceded by “The Alcotts” and “Thoreau,” the third and fourth movements of his more famous second Sonata, “Concord, Mass., 1840-1860,” a tribute to the literary giants of that little town. Taken together, these composition offer an unforgettable view of Ives’s unique vision of music that is both universal and deeply American.
