Boston appeared unremarkable and he guest conducted at the Bayreuth Festival as the conductor of the BSO. Phi Mu Alpha Sinfonia music fraternity made him an honorary member in 1916 and he judged a piano competition in the spring of 1917. On October 2–5, 1917, he led the BSO in historic recordings for the Victor Talking Machine Company in Camden, New Jersey. The sessions included works by Tchaikovsky, Wolf-Ferrari, Berlioz, Beethoven, and Wagner. Philip Hale, music critic of the Boston Herald during Muck's years there, wrote: "He stands there calm, undemonstrative, graceful, elegant, aristocratic; a man of singularly commanding and magnetic personality even in repose. The orchestra is his speech, the expression of the composer's music as it appeals to the conductor's brain, heart and soul." National Anthem controversy When the United States entered World War I in the spring of 1917, Muck offered to resign his position as music director of the BSO. He anticipated that his natural sympathies for Germany, where he was born and spent most of his career despite his Swiss citizenship, might give offense.

Nevertheless, he programmed all-German concerts on his first tour of American cities following U.S. entry into the war, which some found not at all sensitive to the public's mood in wartime. In the fall of 1917, some orchestras like the New York Orchestra Society started performing "The Star-Spangled Banner" at all their concerts. Members of the BSO management team discussed programming the anthem for weeks, but without any sense of the issue's importance. Moreover, the orchestra's manager, Charles A. Ellis, did not want to embarrass Muck by asking him to do it, given Muck's close attachment to Germany and his personal relationship with the Kaiser. The BSO performed regularly at Infantry Hall in Providence, Rhode Island, where the Providence Journal had been attacking Muck for his ties to the Kaiser. The BSO's managers anticipated there might be trouble during their October 1917 visit. One member of
