in residence". Michailidis also conducted the GNO Orchestra & Choir in two novel productions of Richard Wagner's Operas: Tristan und Isolde (2015, staged by Yiannis Kokkos) and Lohengrin (2017, staged by Anthony McDonald), which were both heard for the first time in Greek history, in their integral, original and scenic versions. One of Michailidis most successful long-term achievement was certainly the relocation of the GNO in 2017 from its former venue, the historic Olympia Theater located in the center of Athens, to its newly built headquarters in the Stavros Niarchos Foundation Cultural Center (SNFCC), a state-of-the-art performing arts center designed by famous architect Renzo Piano, which includes new facilities for the National Library of Greece (NLG) and for the Greek National Opera (GNO) (new 1,400-seat Opera Hall), located in a 210,000 m² park nearby Athens center, in Palaio Faliro, on the Athens riviera. Notably, in 2014, before the move, Michailidis conducted a strikingly poetic live performance of the GNO orchestra on the construction site of the SNFCC, during which 10 tower cranes literally “danced” to the music of Gustav Holst's The Planets, with Renato Zanella's unique choreography. Theater Erfurt & Erfurt Philharmonic Orchestra (2018-) After completing two mandates at the GNO, and a few months only before GNO's final installation in the SNFCC, the Greek Ministry of Culture announced to the general surprise in February 2017 that Michailidis contract will not be extend beyond that season, provoking a great shock in public opinion. Following his invitation at the Opera House of Shanghai to conduct Donizetti's La Fille du régiment (for its first presentation on Chinese soil) and at the Theater Erfurt to conduct the rare Giulietta e Romeo of Riccardo Zandonai, it was announced, late 2017, that Michailidis was chosen by the direction of the Theater Erfurt and by the members the Erfurt Philharmonic Orchestra to become their new Generalmusikdirektor (GMD) for the next two seasons. For his 2018/19 season debut, Michailidis conducted a new production of Bizet's Carmen at the 2018 Erfurt summer's open-air festival, DomStufen-Festspiele (which takes place on the Cathedral Square, seating up to 2,000 spectators). He also conducted for the following seasons Lehár's Die Lustige Witwe (2019), Rimsky-Korsakov's The Tale of Tsar Saltan (2019), Verdi's Aida (2019), Nabucco (2020, 2022) and Luisa Miller (2022), Wagner's Lohengrin (2020) and Puccini's Manon Lescaut (2021), as well as a series of symphonic works of Mozart, Beethoven, Schumann, Brahms, Mahler,
