[1][2] At the height of his career, he was greatly admired for his range and versatility, having possessed a sufficiently accomplished bel canto technique which enabled him to sing the music of Handel, Mozart and Rossini but with enough vocal power to handle the more overtly dramatic roles in Verdi, Puccini, and Meyerbeer operas.

As his repertoire expanded he worked extensively in European theaters notably in Berlin, Hamburg, London, Paris, Milan, and Vienna in addition to summer festivals in Aix-en-Provence, Glyndebourne, Pesaro, and Salzburg.

Ramey has sung in Mozart's Don Giovanni and The Marriage of Figaro and, in the bel canto repertoire, in Rossini's Semiramide, The Barber of Seville, Il Turco in Italia, L'italiana in Algeri, and La Gazza Ladra; in Donizetti's Anna Bolena and Lucia di Lammermoor and Bellini's I puritani.

In 1990, he sang the role of Joe in Jerome Kern's Show Boat in a concert performance at Avery Fisher Hall with Jerry Hadley and Frederica von Stade.

[4] A number of previously obscure operas with strong bass/bass-baritone roles have been revived solely for Ramey, such as Verdi's Attila, Rossini's Maometto II and Massenet's Don Quichotte.

[10] Ramey has made an exceptionally high number of recordings documenting many of his main operatic roles as well as collections of miscellaneous arias, other classical pieces, and crossover discs of popular American music.
