Sequoia is an orchestral composition by the American composer Joan Tower.  The work was commissioned by the American Composers Orchestra with support from the Jerome Foundation.  It was first performed on May 18, 1981 in Alice Tully Hall by the American Composers Orchestra under the conductor Dennis Russell Davies.

Martinů wrote 6 symphonies, 15 operas, 14 ballet scores and a large body of orchestral, chamber, vocal and instrumental works.  Martinů became a violinist in the Czech Philharmonic Orchestra, and taught music in his home town.  In 1923 Martinů left Czechoslovakia for Paris, and deliberately withdrew from the Romantic style in which he had been trained.  In the 1930s he experimented with expressionism and constructivism, and became an admirer of current European technical developments, exemplified by his orchestral works "Half-time" and "La Bagarre".  He also adopted jazz idioms, for instance in his "La revue de cuisine" ("Kitchen Revue").

Sir Arthur Seymour Sullivan MVO (13 May 1842 – 22 November 1900) was an English composer.  He is best known for his series of 14 operatic collaborations with the dramatist W. S. Gilbert, including "H.M.S. Pinafore", "The Pirates of Penzance" and "The Mikado".

The Pleasures of the Enchanted Island (French: Les" "plaisirs de l’Île enchantée) was a multi-day performance presented to the court of King Louis XIV of France at Versailles.  It was staged to celebrate the beginning of the building campaigns for the Chateau de Versailles.  In particular, the intention was to acquaint those involved in its construction, the King's wife, mother, lovers, mistresses, and family in general to cotillon style ball and overall culture.

Igor Štuhec (born 15 December 1932) is a contemporary Slovenian composer, who lives in Ljubljana and Maribor.  He studied composition at the Ljubljana Academy of Music under Lucijan Marija Škerjanc and Matija Bravničar.  He continued his studies at the Vienna Academy of Music and Dramatic Art under Hanns Jelinek, and also at the Darmstädter Ferienkurse.  After some early neo-classical orchestral works that show his mastery of traditional techniques, Štuhec gradually moved towards the adoption of new techniques in the early 1960s.  Although in 1955 he had produced a musique concrète composition in "Biological Transformation", the radical change came with the chamber pieces "Situacija" (1963) and "Silhuete" (1964) and the orchestral "Differentiations" (1964), all of which exhibit his assimilation of 12-note and aleatory procedures.  Štuhec's skill is particularly evident in miniatures such as the "Minikoncert", where his writing is at its most delicate and the textures are almost always crystal clear.  A later group of orchestral works extending his textural techniques, notably the concertos and the three "Entuziazmi" pieces, display a vivid imagination and a strong rhythmic momentum.  Also among his works are two operas, "Zupanova Micka" (1948) and
