Little known today, mainly because almost no sopranos other than Mme. Caballé can sing it, Gemma di Vergy was for some years in the 19th century the most popular opera by Donizetti, produced more often than Lucia, Don Pasquale, L'elisir d'amore, you name it. This great recording is of the first revival of the opera in almost 75 years, a must for all Donizetti and/or Caballé fans. Live performance, Naples, December 12, 1975.
