World War I prevented Salmond from developing his international career further at that time, but he resumed building a reputation in
chamber music after the war. His performances in this period included the premieres, on 21 May 1919, of
Edward Elgar's
String Quartet in E minor and
Piano Quintet in A minor at the Wigmore Hall (as the Bechstein Hall had now become). After Salmond's performance of his quartet, Elgar entrusted Salmond with the solo part for the debut of his most personal and heartfelt work, his
Cello Concerto in E minor with the London Symphony Orchestra at the
Queen's Hall. The premiere, on 26 October 1919, proved to be a disaster. The performance was scheduled such that
Albert Coates, the conductor of the London Symphony, would conduct the rest of the programme and Elgar himself would conduct the concerto. Coates, a self-important man, was well known for using up to forty-five minutes of his hour of rehearsal time lecturing his players. After Coates consumed an hour of Elgar's rehearsal time, Elgar—who was until that time waiting offstage for his chance to rehearse—uncharacteristically exploded with anger. The severely under-rehearsed performance which followed received scathing reviews, with
Ernest Newman stating that "the orchestra made a public exhibition of its miserable self". Elgar later said that if it weren't for Salmond's diligent work in preparing the piece, he would have pulled it from the concert entirely. On 10 November 1920, the inaugural concert of the City of Birmingham Orchestra (later the
City of Birmingham Symphony Orchestra) was given at
Birmingham Town Hall, with Elgar conducting a concert of his own works, including the first performance of his Cello Concerto in that city, with Salmond as the soloist. ==Career in America==
