New Symphony Orchestra

　Born in 1860, Mahler was one of the last of the German late Romantic composers. 37 years old, he reached the peak of his career as artistic director of the Vienna Court Opera. 49 years old, he became conductor of the New York Philharmonic, where he completed his 9th Symphony, and then began to develop the idea for a more advanced symphony, the 10th. After completing the Ninth Symphony, he began to develop the idea for the Tenth Symphony, which would go even further. However, he died of septicemia at the age of 51 after suffering from pharyngitis.
　The first movement of the unfinished Tenth Symphony is almost complete, but the second through fifth movements remain as rough sketches. The International Mahler Society has published only the first movement, and although the first movement is often performed alone, there are several complete versions of the work in supplemental form. Among them, the one by British musicologist Derrick Cook is widely accepted.
　Mahler apparently told his wife Alma to burn the score of No. 10, but she left it as a memento and published a facsimile of the autograph score. He asked Alma's son-in-law, Kruschenek, to make corrections to the score, and he completed the first movement, which was almost unchanged, and the third movement, for which an orchestral score had been prepared halfway through, and the Vienna Philharmonic Orchestra gave the premiere. Several people who saw the facsimile version found the music impressive and possible to be added. One such person was Cook, whose performance was broadcast in 1960 in a BBC special commemorating Mahler's centenary. Alma was outraged and banned the performance, but when he heard the tape of the performance, he was so moved that he lifted the ban, and Cook continued to make additions to the music, which came to be recognized as highly reliable.

　Schreker, born in 1876, was Jewish like Mahler and studied at the Vienna Conservatory, where he composed while working as a conductor.
　His unique style, which is basically tonal but incorporates advanced techniques, has been described by conductor Eschenbach as "taking Mahler's symphonic writing style to a whole new level.
　Schreker himself was appointed professor at the Vienna Conservatory of Music and became an influential composer, but he died of a stroke at the age of 55 after being oppressed by the Nazis.
　The "Prelude to a Drama" was compiled before the completion of the opera "Branded People" by adding music for other scenes to the prelude to the opera.
