アルノルト・シェーンベルクの『モーゼとアロン』をのちに完成させた音楽家はいる？
Moses und Aron (English: "Moses and Aaron") is a three-act opera by Arnold Schoenberg with the third act unfinished. The German libretto is by the composer after the Book of Exodus. Hungarian composer Zoltán Kocsis completed the last act, with Schoenberg's heirs' permission, in 2010, but "Moses und Aron" was almost always performed as Schoenberg left it in 1932, with only two of the planned three acts completed.
