Symphony No. 2, Op. 132, Mysterious Mountain is a three-movement orchestral composition by the American composer Alan Hovhaness. The symphony was commissioned by the conductor Leopold Stokowski and the Houston Symphony, and premiered live on NBC television in October 1955 on the Houston Symphony's first program with Stokowski as conductor. A popular recording of the work, released in 1958 with the Chicago Symphony Orchestra performing under Fritz Reiner, is often regarded as the foremost performance of the piece.
Anton Bruckner's Symphony No. 7 in E major (WAB 107) is one of his best-known symphonies. It was written between 1881 and 1883 and was revised in 1885. It is dedicated to Ludwig II of Bavaria. The premiere, given under Arthur Nikisch and the Gewandhaus Orchestra in the opera house at Leipzig on 30 December 1884, brought Bruckner the greatest success he had known in his life. The symphony is sometimes referred to as the "Lyric", though the appellation is not the composer's own, and is seldom used.
