By the late 1930s, Bliss was no longer viewed as a modernist; the works of his juniors William Walton and the youthful Benjamin Britten were increasingly prominent, and Bliss's music began to seem old-fashioned. His last large-scale work of the 1930s was his Piano Concerto, composed for the pianist Solomon, who gave the world premiere at the World's Fair in New York in June 1939. Bliss and his family attended the performance and then stayed on in the US for a holiday. While they were there, the Second World War broke out. Bliss initially stayed in America, teaching at the University of California, Berkeley. He felt impelled to return to England to do what he could for the war effort, and in 1941, leaving his wife and children in California, he made the hazardous Atlantic crossing.
