He arrives in Saint Petersburg on September 25, for two months in the two Russian capitals. In his repertoire he had the work of his great triumphs, La Favorita . In Moscow he sings with the great Adelina Patti. The great impact on the Russian public earned him his contract for 1874-1875. In the spring of that year he sings in Vienna, again with Patti. After the Palermo season. Gayarre's wealthy career revolutionized wealthy Italy. They already called him the great tenor.
But this title had to be ratified at La Scala. He was to debut with La Favorita , his favorite work. And the day of his debut arrived, before the knowledgeable and feared public. And the great tenor earned the title, signed it, attracting the Milanese with his magic. The music critic Filippo Filippe ended his verdict like this: "...in a word, we witnessed last night at La Scala, not the debut of an artist, but the consecration of a singing genius". That night when Gayarre entered the Café Biffi, a crowd crowded into the Víctor Manuel Gallery to meet the marvelous tenor, to contemplate him, to see him eat or drink coffee. This occurred on January 2, 1876.
