Question: What is the nationality of the composer of "Radical Dreamers"?  

<P0-S0> The Viola Concerto by William Walton was written in 1929 for the violist Lionel Tertis at the suggestion of Sir Thomas Beecham. <P0-S1>  The concerto carries the dedication "To Christabel" (Christabel McLaren, Lady Aberconway). <P0-S2>  But Tertis rejected the manuscript, and composer and violist Paul Hindemith gave the first performance. <P0-S3>  The work was greeted with enthusiasm. <P0-S4>  It brought Walton to the forefront of British classical music. <P0-S5>  In "The Manchester Guardian", Eric Blom wrote, "This young composer is a born genius" and said that it was tempting to call the concerto the best thing in recent music of any nationality. <P0-S6>  Tertis soon changed his mind and took the work up. <SEP> <P1-S0> The Polar Music Prize is a Swedish international award founded in 1989 by Stig Anderson, best known as the manager of the Swedish band ABBA, with a donation to the Royal Swedish Academy of Music. <P1-S1>  The award is annually given to one contemporary musician and one classical musician. <P1-S2>  Exceptions were made in 2001, when it was awarded to three musicians (one composer, one contemporary musician and one inventor), and 2003, when it was awarded only to one musician. <P1-S3>  Without any restrictions of nationality, the prize is to be "awarded for significant achievements in music and/or musical activity, or for achievements which are found to be of great potential importance for music or musical activity, and it shall be referable to all fields within or closely connected with music". <P1-S4>  The prize has been called the "Nobel Prize of Music" in Sweden. <SEP> <P2-S0> The "Chrono" series is a video game franchise developed and published by Square Enix (formerly Square). <P2-S1>  It began in 1995 with the time travel role-playing video game "Chrono Trigger", which spawned two continuations, "Radical Dreamers" and "Chrono Cross". <P2-S2>  The music of "Chrono Cross" was composed by Yasunori Mitsuda, the main composer of "Chrono Trigger" and "Radical Dreamers". <P2-S3>  "Chrono Cross" has sparked a soundtrack album, released in 1999 by DigiCube and re-released in 2005 by Square Enix, and a greatest hits mini-album, published in 2000 by Square along with the North American release of the game. <P2-S4>  "Radical Dreamers", the music of which heavily inspired the soundtrack of "Chrono Cross", has not sparked any albums, though some songs from its soundtrack were reused in "Chrono Cross". <P2-S5>  An album of arrangements of "Chrono Cross" songs was first announced by Mitsuda in 2005, and later intended to be released to coincide with the tenth anniversary of the game in 2009; its release data was pushed back several times since then. <P2-S6>  In 2015, Mitsuda via Square Enix released an album of arranged music from "Chrono Trigger" and "Chrono Cross" entitled "To Far Away Times" to commemorate the 20-year anniversary of "Chrono Trigger". <SEP> <P3-S0> Yasunori Mitsuda (光田 康典 , Mitsuda Yasunori , born January 21, 1972) is a Japanese composer, musician, and sound producer known primarily for his work in video games, among other media. <P3-S1>  He is best known for his compositions in the "Chrono", "Xeno", "Shadow Hearts", and "Inazuma Eleven" series of games, as well as titles such as "Mario Party", "Soma Bringer", and "Soul Sacrifice".
