M. Duponchel, the manager of the Opera in Paris, hastened to London to hear Alboni sing, and immediately offered her an engagement. In October, 1847, she made her Parisian _debut_. Her first appearance in concert was with Alizard and Barroilhet. "Many persons, artists and amateurs," said Fiorentino, "absolutely asked on the morning of her _debut_, Who is this Alboni? Whence does she come? What can she do?" And their interrogatories were answered by some fragments of those trifling and illusory biographies which always accompany young vocalists. There was, however, intense curiosity to hear and see this redoubtable singer who had held the citadel of the Royal Italian Opera against the attraction of Jenny Lind, and the theatre was crowded to suffocation by rank, fashion, beauty, and notabilities on the night of her first concert, October 9th. When she stepped quietly on the stage, dressed in black velvet, a brooch of brilliants on her bosom, and her hair cut _a la Titus_, with a music-paper in her hand, there was just one thunder-clap of applause, followed by a silence of some seconds. She had not one acknowledged advocate in the house; but, when Arsace's cavatina, "Ah! quel giorno," gushed from her lips in a rich stream of melodious sound, the entire audience was at her feet, and the critics could not command language sufficiently glowing to express their admiration. "What exquisite quality of sound, what purity of intonation, what precision in the scales!" wrote the critic of the "Revue et Gazette Musicale." "What _finesse_ in the manner of the breaks of the voice! What amplitude and mastery of voice she exhibits in the 'Brindisi'; what incomparable clearness and accuracy in the air from 'L'ltaliana' and the duo from 'Il Barbiere!' There is no instrument capable of rendering with more certain and more faultless intonation the groups of rapid notes which Rossini wrote, and which Alboni sings with the same facility and same celerity. The only fault the critic has in his power to charge the wondrous artist with is, that, when she repeats a morceau, we hear exactly the same traits, the same turns, the same fioriture, which was never the case with Malibran or Cinti-Damoreau."
