Besides whom are two famous announcements, yet to come from Europe: the French tenor, Roger, and the German basso, Formes. The orchestra and chorus are, we suppose, as usual; the conductor better; he is Herr Anschütz, who has had experience in London, and who subdues his orchestra to sympathetic support of the singers. With Max it is the other way; he loves to ride full swing upon the top of his forces, brass and all, _fortissimo_, conquering and to conquer. Is "Il Trovatore" wanted, everlasting "Trovatore,"--music that whirls and fascinates, possessed and driven by one fixed idea of burning at the stake, with furies of love and jealousy to match,--they borrow from the other company (under the "amicable" treaty) Brignoli, of the golden tenor voice, who sings so sweetly and sulks so proudly lazy, and Amodio, that ton of juvenile humanity, whose weighty baritone and eagerness to please make up for the see-saw alternation of his two only expressions and gesticulations,--those of vulgar love-making and mock-heroical revenge. These, with Gazzaniga, the charming, lively, natural Gazzaniga, whose voice _is_ fresh, and who can sing and act so charmingly in genial music, such as Donizetti's "Elisir d' Amore," with also Assoni, the buffo, and Coletti, the bass, compose the year-old and tried nucleus of the Philadelphia opera, which opened the first Monday in October. To these are added new attractions, in the shape of old celebrities from Europe: namely, Ronconi, the great _Don Giovanni_ of the London opera; Tagliafico, the basso; Stecchi-Bottardi, tenor from Her Majesty's; Signora Ramos, prima donna from Turin; Signora Tagliafico; and greatest of all, to come when he has got through with the Russians, the famous tenor, Tamberlik.
