I have a test where I am given the following article, what is an answer for the question: What is the name of the person that was influenced by Ravel? ?

Walton was a slow worker. Both during composition and afterwards he would continually revise his music; he said, "Without an india-rubber I was absolutely sunk." Consequently, his total body of work from his sixty-year career as a composer is not large. Between the first performance of Façade in 1923, for example, and that of the Sinfonia Concertante in 1928, he averaged only one small piece a year. Of his work as a whole, Byron Adams in Grove's Dictionary of Music and Musicians writes:
Walton's music has often been too neatly dismissed by a few descriptive tags: "bittersweet", "nostalgic" and, after World War II, "same as before". Such convenient categorizations ignore the expressive variety of his music and slight his determination to deepen his technical and expressive resources as he grew older. His early discovery of the basic elements of his style allowed him to assimilate successfully an astonishing number of disparate and apparently contradictory influences, such as Anglican anthems, jazz, and the music of Stravinsky, Sibelius, Ravel and Elgar.
The writer adds that Walton's allegiance to his basic style never wavered and that this loyalty to his own vision, together with his rhythmic vitality, sensuous melancholy, sly charm and orchestral flair, gives Walton's finest music "an imperishable glamour". Another biographer of Walton, Neil Tierney, writes that although contemporary critics felt that the post-war music did not match Walton's pre-war compositions, it has become clear that the later works are "if emotionally less direct, more profound."
