Teodorini. From 1992 to 1996, he was Music Director of Germany's most renowned theater, the Berliner Ensemble, founded by Bertolt Brecht, where he collaborated with the celebrated stage director Peter Zadek. Frey was the first American to hold a position at the Berliner Ensemble, as well as being the theater's first non-German Music Director; his historic predecessors who held the same music directorship included the composers Kurt Weill, Hanns Eisler, and Paul Dessau. While there, Zadek and Frey's artistic collaboration made theater history by producing several revolutionary and innovative productions. They adapted Vittorio De Sica's film Miracle in Milan (Miracolo e Milano) for the stage using the actual entire dialogue script from the film. Frey devised the idea of restoring the entire original film score and performing it live throughout the play using exactly the same music cues as in the film, marking the first time this technique was ever used. He repeated this method for a subsequent production in Austria of a stage version of the film Arsenic and Old Lace. For Miracle in Milan, Frey and the production were nominated for a Berlin Theater Critics' Prize. In addition to directing the music for 7 other large productions at BE, Frey also produced and directed the Berliner Ensemble's A Paul Dessau Evening, a multimedia retrospective of the musical and dramatic works of the theater's music director of the 1950s. Piano/organ performances As pianist and organist, Frey has performed with over 30 symphony orchestras including the Berlin Philharmonic, San Francisco Symphony, Leipzig Gewandhaus Orchestra, Munich Symphony Orchestra, Hollywood Bowl Orchestra, the Vienna Radio Symphony Orchestra (ORF), Rundfunk-Sinfonieorchester Berlin (Berlin Radio Symphony Orchestra), Orchestra dell'Arena di Verona, Deutsches Symphonie-Orchester Berlin, Rome Philharmonic Orchestra, the orchestra of the Teatro Regio di Torino (with whom he appeared as soloist in the 3 inaugural concerts opening Torino's newly restored opera house), the Cairo Symphony Orchestra, Orquesta Sinfónica del Estado de México (State of Mexico Symphony Orchestra), Bohemian Symphony Orchestra Prague, the chamber orchestra of the Palacio de Bellas Artes (the chamber orchestra of the opera house of Mexico City), Orchestra Filarmonica Italiana, Monterrey (Mexico) Symphony Orchestra (UANL), Orchestra Sinfonica Siciliana and Berliner Bach Akademie among others, under such conductors as Claudio Abbado, John Mauceri, Michael Tilson Thomas and Howard Shore. He frequently played recitals with the renowned Grammy Award-winning tenor, Jerry Hadley. Frey has performed chamber music with violinist Ruggiero Ricci and the Vermeer
