A rock opera is a work of rock music that presents a storyline told over multiple parts, songs or sections in the manner of opera. A rock opera differs from a conventional rock album, which usually includes songs that are not unified by a common theme or narrative. More recent developments include metal opera and rap opera (sometimes also called hip-hopera). A rock opera tells a coherent story, and may involve songs performed as if sung by separate characters in a drama, as in classical opera.

A rock opera may or may not be presented in a staged performance. In recorded form it can be similar to a concept album (of which it is a subset), though the latter may simply set a mood or maintain a theme.

The July 4, 1966 edition of RPM Magazine (published in Toronto) notes that "Bruce Cockburn and Mr [William] Hawkins are working on a Rock Opera, operating on the premise that to write you need only 'something to say'." The Cockburn / Hawkins rock opera seems not to have been completed, though some songs from the project may be among the Cockburn and Hawkins compositions that appeared on 3's a Crowd's 1968 album, Christopher's Movie Matinee.

Lindsey Stirling (born on September 21, 1986) is an American violinist, musician, dancer, performance artist, and composer. In 2010 she competed on the fifth season of America's Got Talent. Stirling is noted for her versatility performing music from country to hip hop.

At the age of 23 Stirling was a quarter-finalist on the fifth season of America's Got Talent where she was known as the ‘Hip Hop Violinist’. After Stirling's performance, Sharon Osbourne said, "Wow... we love you Lindsey!” and Piers Morgan called her performance "Electrifying!".

At the age of 5, after being influenced by the classic music records played by her father, Stirling requested the opportunity to learn and play the violin.

Stirling was classically trained through private lessons for 12 years. When she was 16, she joined a rock band with four friends called Stomp on Melvin. As part of her experience with Stomp on Melvin, Stirling wrote a solo violin rock song, and her performance helped her to win both the title of Arizona’s Jr. Miss in 2005 and the talent category of the National Jr. Miss Pageant. As of May 2, 2012, Stirling is 5'3" tall.

Viktor Dyk (Czech pronunciation: [ˈvɪktor ˈdɪk]) (December 31, 1877, Pšovka u Mělníka, Austria-Hungary – May 14, 1931, near the island of Lopud, Yugoslavia) was a well-known Czech poet, prose writer, playwright, politician and political writer.

Viktor Dyk studied at a gymnasium in Prague (one of his teachers was Alois Jirásek) and then at the Faculty of Law of Charles University in Prague.

In 1911, he became involved in politics and joined the Státoprávně pokroková strana. During the First World War, he was imprisoned in Vienna for his resistance activities against Austria-Hungary. In 1918, he co-founded the Czechoslovak National Democratic Party (in Czech: Československá národní demokracie).

His political views were conservative and nationalist. In the times of the First Republic of Czechoslovakia, Viktor Dyk was one of the prominent intellectual opponents of the leftish president Tomáš Garrigue Masaryk.

Viktor Dyk died of a heart failure while swimming in the sea near the island of Lopud.

Mozart, l'opéra rock ("Mozart, the rock opera") is a French musical directed by Olivier Dahan and produced by Dove Attia and Albert Cohen. The show uses both pop-rock compositions and music composed by Wolfgang Amadeus Mozart.

The musical premiered on 22 September 2009 at the Palais des Sports de Paris, where it continued until 3 January 2010. From 4 February 2010 until 3 July 2010, it went on tour in France, Belgium and Switzerland. It returned to Paris between 9 November 2010 and 9 January 2011. A second tour began on 4 February 2011 and close on 9 July 2011 at the Palais Omnisports de Paris-Bercy, accompanied by a symphonic orchestra.

Act I The show opens with the accession of Hieronymus von Colloredo-Mannsfeld to the archbishop of Salzburg. Unlike the previous ruler, Colloredo is discouraging of the arts, which does not bode well for the Mozart family, who work for him. When Leopold Mozart requests leave to tour with his seventeen-year-old son and musical prodigy, Wolfgang, Colloredo refuses and suggests Leopold and Wolfgang quit if they are dissatisfied. Leopold and his daughter, Wolfgang's older sister, Nannerl, bemoan the state of Salzburg and its subservient people (Penser l'Impossible). Wolfgang appears, tumbling out from under the skirts of several women he's been chasing, and proceeds to be told exactly what Colloredo told Leopold: His leave has been denied.
