Question: Who was the composer of both the "Christmas Symphony" and "Symphony No.3"?

<P0-S0> An unfinished symphony is a fragment of a symphony, by a particular composer, that musicians and academics consider incomplete or unfinished for various reasons. <P0-S1>  The archetypal unfinished symphony is Franz Schubert's Symphony No. 8 (sometimes called "Schubert's Unfinished Symphony"), written in 1822, six years before his death. <P0-S2>  It features two fully orchestrated movements. <P0-S3>  While it seems clear from sketches that Schubert set out to create a traditional four-movement symphony, this has been the subject of endless debate. <P0-S4>  Schubert wrote the symphony for the Graz Musical Society, and gave the manuscript to his friend Anselm Hüttenbrenner, in his capacity as its representative. <P0-S5>  However, Hüttenbrenner did not show the score to the society at that time, nor did he reveal the existence of the manuscript after Schubert died in 1828, but kept it a secret for another 37 years. <P0-S6>  In 1865, when he was 76 (three years before his death), Hüttenbrenner finally showed it to the conductor Johann von Herbeck, who conducted the extant two movements on 17 December 1865 in Vienna, adding the last movement of Schubert's third symphony as the finale. <P0-S7>  Music historians and scholars then toiled to "prove" the composition was complete in its two-movement form, and indeed, in that form it became one of the most popular pieces in the late 19th century classical music repertoire, and remains one of Schubert's most popular compositions. <SEP> <P1-S0> Krzysztof Eugeniusz Penderecki ( ; ] ; born 23 November 1933) is a Polish composer and conductor. " <P1-S1> The Guardian" has called him Poland's greatest living composer. <P1-S2>  Among his best known works are his "Threnody to the Victims of Hiroshima", "Symphony No. 3", "St. Luke Passion", "Polish Requiem", "Anaklasis", "Utrenja", four operas, eight symphonies and other orchestral pieces, a variety of instrumental concertos, choral settings of mainly religious texts, as well as chamber and instrumental works. <SEP> <P2-S0> Lowell Liebermann’s Symphony No. 2, Op. 67 (1999) is a symphony for large orchestra and SATB chorus, with texts adapted from the poetry of Walt Whitman. <P2-S1>  It is about 40 minutes long, and arranged into four movements to be played without a break. <P2-S2>  It was commissioned by Ford Lacy and Cece Smith for the Dallas Symphony Orchestra and Chorus’ centennial celebration. <P2-S3>  The work was premiered in 2000, with Andrew Litton conducting the Dallas Symphony Orchestra and Chorus. <P2-S4>  The Second Symphony was very favorably received at its premiere, with TIME describing it as, “Now brazen and glittering, now radiantly visionary...the work of a composer unafraid of grand gestures and openhearted lyricism.” <P2-S5>  However, the symphony has since received harsh criticism due to its exceptionally free embrace of tonality and its distinctly optimistic outlook. <P2-S6>  Scott Cantrell in particular has denounced the Second Symphony as "foolhardy" in the "cynical" environment of today. <P2-S7>  The Second Symphony was recorded in 2000 on the Delos International label with Andrew Litton conducting the Dallas Symphony Orchestra and Chorus. <SEP> <P3-S0> Polish composer Krzysztof Penderecki wrote his Symphony No. 2 during the winter of 1979–80. <P3-S1>  Sometimes referred to as the "Christmas Symphony" (quotations of the Christmas carol "Silent Night" occur repeatedly throughout the symphony), neither the score nor the parts (Schott Music, Mainz 45 791) make any reference to this moniker.
