  Title: Visions fugitives
  Passage: Visions fugitives, Op. 22, are a series of short piano pieces composed by Russian composer Sergei Prokofiev (1891–1953) between 1915 and 1917.  They were premiered by Prokofiev on April 15, 1918 in Petrograd, Soviet Union.  They were written individually, many for specific friends of Prokofiev's, and he originally referred to them as his "doggies" because of their "bite".  In August 1917, Prokofiev played them for Russian poet Konstantin Balmont, and others, at the home of a mutual friend.  Balmont was inspired to compose a sonnet on the spot, called "a magnificent improvisation" by Prokofiev who named the pieces ""Mimolyotnosti"" from these lines in Balmont's poem: ""In every fleeting vision I see worlds, Filled with the fickle play of rainbows"".  A French-speaking friend at the house, Kira Nikolayevna, immediately provided a French translation for the pieces: "Visions Fugitives".  Prokofiev often performed only a couple of them at a time as encores at the end of his performances.

  Title: Michael Kibbe
  Passage: Michael Kibbe (born 1945) is an American contemporary classical music composer born in San Diego, California.  He has composed over 240 concert works and created numerous arrangements.  His writing covers many musical styles, encompassing tonal, modal and non-diatonic languages.  His style often incorporates modern structures but is still accessible to the popular classical listener.  Some of his works come right of the Romantic Era yet his style in some writings has been compared to Prokofiev.  There are influences of American composer Gershwin in the Serenade Number 2 for two clarinets that seem at once blues, jazz and classical.  His music can often reflect themes that bring to mind different cultures.
  Title: Sergei Prokofiev
  Passage: Sergei Sergeyevich Prokofiev ( ; Russian: Сергей Сергеевич Прокофьев , "Sergej Sergejevič Prokofjev" ; 27 April 1891 – 5 March 1953) was a Soviet composer, pianist and conductor.  As the creator of acknowledged masterpieces across numerous musical genres, he is regarded as one of the major composers of the 20th century.  His works include such widely heard works as the March from "The Love for Three Oranges," the suite "Lieutenant Kijé", the ballet "Romeo and Juliet" – from which "Dance of the Knights" is taken – and "Peter and the Wolf."  Of the established forms and genres in which he worked, he created – excluding juvenilia – seven completed operas, seven symphonies, eight ballets, five piano concertos, two violin concertos, a cello concerto, a Symphony-Concerto for cello and orchestra, and nine completed piano sonatas.
  Title: Piano Concerto No. 2 (Prokofiev)
  Passage: Sergei Prokofiev set to work on his Piano Concerto No. 2 in G minor, Op. 16, in 1912 and completed it in 1913.  But this concerto is lost; the score was destroyed in a fire following the Russian Revolution.  Prokofiev reconstructed the work in 1923, two years after finishing his Third Concerto, and declared it to be “so completely rewritten that it might almost be considered [Concerto] No. 4”; indeed its orchestration has features that clearly postdate the 1921 concerto.  Performing as solo pianist, Prokofiev premiered this surviving “No. 2” in Paris on 8 May 1924 with Serge Koussevitzky conducting.  It is dedicated to the memory of Maximilian Schmidthof, a friend of Prokofiev's at the St. Petersburg Conservatory who had killed himself in 1913.
