Radical Computer Music: The term Radical Computer Music was coined by the Danish/Faroese musician/artist Parl Kristian Bjørn Vester, aka Goodiepal or Gæoudjiparl van den Dobbelsteen, while a teacher in composition at the Royal Academy of Music in Aarhus, Denmark, between 2004-2008.  The term relates to the ongoing project "Mort Aux Vaches Ekstra Extra", which is a compositional game scenario conceived by Goodiepal in 2004 questioning the role of the composer, time, notation and media.  Radical Computer Music has been presented frequently by Goodiepal at numerous lectures, performances and exhibitions throughout the western world since 2007.  It is fundamentally music notated, not "by" computer networks but "for" computer networks, as a gesture towards the machine and the artificial intelligence expected to develop from it.  The compositional ideas behind Radical Computer Music are currently among the most debated theories in modern European theoretical composition.

Viola Concerto (Walton): The Viola Concerto by William Walton was written in 1929 for the violist Lionel Tertis at the suggestion of Sir Thomas Beecham.  The concerto carries the dedication "To Christabel" (Christabel McLaren, Lady Aberconway).  But Tertis rejected the manuscript, and composer and violist Paul Hindemith gave the first performance.  The work was greeted with enthusiasm.  It brought Walton to the forefront of British classical music.  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.  Tertis soon changed his mind and took the work up.
