Ornstein soon moved in a very different direction. He began composing works containing dissonant and startling sounds. Ornstein himself was unsettled by the earliest of these compositions: "I really doubted my sanity at first. I simply said, what is that? It was so completely removed from any experience I ever had." On March 27, 1914, in London, he gave his first public performance of works then called "futurist", now known as modernist. In addition to a Busoni arrangement of three Bach choral preludes and several pieces by Schoenberg, Ornstein played a number of his own compositions. The concert caused a major stir. One newspaper described Ornstein's work as "the sum of Schoenberg and Scriabine squared." Others were less analytical: "We have never suffered from such insufferable hideousness, expressed in terms of so-called music."
