Question: Salaakhen had music by the composer of what nationality?
Context: The Viola Concerto by William Walton was written in 1929 for the violist Lionel Tertis at the suggestion of Sir Thomas Beecham.  The concerto carries the dedication "To Christabel" (Christabel McLaren, Lady Aberconway).  But Tertis rejected the manuscript, and composer and violist Paul Hindemith gave the first performance.  The work was greeted with enthusiasm.  It brought Walton to the forefront of British classical music.  In "The Manchester Guardian", Eric Blom wrote, "This young composer is a born genius" and said that it was tempting to call the concerto the best thing in recent music of any nationality.  Tertis soon changed his mind and took the work up.

The prize has been called the "Nobel Prize of Music" in Sweden.
