Sesto Bruscantini (10 December 1919 – 4 May 2003) was an Italian baritone, one of the greatest buffo singers of the post-war era, especially renowned in Mozart and Rossini.
Bruscantini was born in Civitanova Marche, Marche, Italy. After obtaining a law degree, he turned to vocal studies in Rome, with Luigi Ricci at the Accademia Nazionale di Santa Cecilia. He won a vocal contest organized by RAI in 1947 and made his debut at La Scala in Milan in 1949, as Geronimo in Cimarosa's Il matrimonio segreto.
Bruscantini rapidly established himself in buffo roles in opera by Mozart and Rossini such as Le nozze di Figaro, Don Giovanni, Cosi fan tutte, Il turco in Italia, L'italiana in Algeri, Il barbiere di Siviglia, La Cenerentola but also in works by Donizetti such as L'elisir d'amore, La fille du régiment and Don Pasquale. In some of these works he often alternated roles, from Figaro to the Count in Nozze, Guglielmo to Alfonso in Cosi, Belcore to Dulcamara in Elisir, Malatesta to Pasquale in Don Pasquale, etc. He also took part in many revivals of opera by Pergolesi, Scarlatti and Cimarosa. He even recorded with Marilyn Horne the first modern performance of Antonio Vivaldi's Orlando Furioso.
