The success of a November 2007 filmed run of Simon Boccanegra at the Teatro Comunale di Bologna, opening the season there, led to Mariotti's appointment as the theater's direttore principale, to start the next year, a title he would hold until his promotion in 2014. He replaced Daniele Gatti and effectively embarked upon a major career. Productions in Bologna conducted by Mariotti in his capacities as direttore principale and then direttore musicale have been: I puritani with Flórez and La gazza ladra in 2009; Idomeneo with Francesco Meli, Carmen and La traviata ; La Cenerentola with Laura Polverelli, Ferrero's Risorgimento! and Dallapiccola's Il prigioniero ; Le nozze di Figaro ; Norma with Mariella Devia and Nabucco ; Così fan tutte and, Michael Spyres and Carlos Álvarez, Guillaume Tell in 2014; Die Zauberflöte, the conductor's first German-language project, and, with Gregory Kunde, Un ballo in maschera ; Attila with Ildebrando d’Arcangelo, filmed by RAI TV, and Werther with Flórez ; and in 2017 La voix humaine with Anna Caterina Antonacci and Cavalleria rusticana. Mariotti's duties in Bologna include regular subscription concerts with the Orchestra del Teatro Comunale di Bologna, in its home theater and at the Teatro Auditorium Manzoni, the base of Orchestra Mozart. Beethoven's symphonies have featured prominently in these concerts.
In Pesaro
For thirty years, until early 2017, the opera company in Bologna anchored the Rossini Opera Festival in Pesaro. Accordingly, Mariotti participated in his home town's most visible summer event. Among his projects for the ROF with the Chorus and Orchestra of the Teatro Comunale di Bologna were three filmed operas: a 2010 Sigismondo, a 2012 Matilde di Shabran and a 2013 Guillaume Tell, the first two featuring his future wife, Olga Peretyatko, the latter two starring Flórez. He also conducted the Bologna forces in the Adriatic resort in Rossini's Stabat mater.
In Munich
The conductor has developed a bond with the Münchner Symphoniker, guest-conducting the German ensemble in 2013, 2015 and 2017 in works by Schubert, Mendelssohn and Bruckner, among others. In the same city, in 2017, he debuted at Bavarian State Opera with Semiramide starring Joyce DiDonato.
During the Bologna company's September 2011 tour to Japan, Mariotti led performances of Carmen, starring Nino Surguladze, and I puritani, with Desirée Rancatore, Celso Albelo, Luca Salsi and Nicola Ulivieri, at Tokyo Bunka Kaikan, as well as events outside the capital.
In 2016, Mariotti added I due Foscari to his repertory, conducting it as a return engagement at the Teatro alla Scala. Later the same year, he led his first performances of two French operas, both featuring Flórez: Les Huguenots at the Deutsche Oper in Berlin and the above-mentioned Werther in Bologna.
Personal life
Mariotti married Russian soprano Olga Peretyatko in Pesaro in August 2012, just after a run of Rossini's Matilde di Shabran, o sia Bellezza e Cuor di ferro in which they both participated. She was born in Leningrad in 1980. They live in the Pesaro area, as do Flórez and his wife. The four are close friends; the men were introduced by retired Peruvian tenor Ernesto Palacio, a mentor to Flórez, longtime Pesaro area resident, former artist manager for both the younger tenor and the conductor, and, as of 2018, superintendent of the Rossini Opera Festival.
