Benjamin Britten is one most important British composers from the second half of the twentieth century. Remarkably, he focused on opera, a dying genre, at least in its current form. Britten's contributions however, among which Peter Grimes, The Rape of Lucretia, Gloriana, The Turn of the Screw, and Death in Venice, managed to remain core repertoire for opera companies to this day. Many of these productions included a role for his artistic partner and life companion Peter Pears. Britten also wrote a number of lieder for this tenor, among which his Serenade for tenor, horn and string orchestra. Yet, Britten excelled in many more genres. He wasn't even 20 years old when he composed his brilliant Phantasy for hobo quartet and his friendship with the legendary cellist Rostropovich led to a Cello sonata, three Suites for cello solo and a Symphony for Cello and orchestra in the 1960s.

Britten never became Master of the Queen's Music, yet he surely had feeling for public sentiments. For example, as a pacifist, he taught his people about world peace through his War Requiem from 1962. Britten was an excellent interpreter of his own work, just like Bartók and Stravinsky. Many of his recordings have been matched, but never exceeded.

Zoltán Kodály was a Hungarian composer, born in 1905. If you would read Kodály's biography, you could only do so with increasing astonishment. Not only did he reach the honarable age of 84, throughout his whole life he remained astoundingly prolific - and with great success. Moreover, besides his work as a composer, Kodály was active as a conductor, (ethno-)musicologist, pedagogue, linguist, and philosopher. And in each of these areas, he had a pioneering role, always with exceptional passion and dedication. To name but one example: together with his friend Belá Bartók he worked on a ten volume reference guide to Hungarian music, which appeared from 1951 with each volume spanning more than a thousand pages.
Yet, Kodály gained acclaim for his compositions as well, with his Psalmus hungaricus (1923) en his opera Háry János (1926) as the pinnacles of his musical career. The core of his body of work consists of vocal music, in particular works for choir, but his instrumental music is just as impressive. His master piece Laudes Organi, written one year before his death, truly proves that Kodály's creative energy stayed with him to the bitter end.

Sir John Kenneth Tavener was an English composer, known for his extensive output of religious works, including The Protecting Veil, Song for Athene and The Lamb.
Tavener first came to prominence with his cantata The Whale, premiered in 1968. Then aged 24, he was described by The Guardian as "the musical discovery of the year", while The Times said he was "among the very best creative talents of his generation." During his career he became one of the best known and popular composers of his generation, most particularly for The Protecting Veil, which as recorded by cellist Steven Isserlis became a bestselling album, and Song for Athene which was sung at the funeral of Princess Diana. The Lamb featured in the soundtrack for Paolo Sorrentino's film The Great Beauty. Tavener was knighted in 2000 for his services to music and won an Ivor Novello Award.

Gustav Holst is a composer nobody seems to know, evne though everyone knows The Planets. This lack of relative fame is a mystery, because the quality of his works for choir and orchestra (including some amazing works for brass orchestra) is often high. Perhaps this can be explained by his aversion to public appearance. After the succes of The Planets he focused on more introvert topics, which resulted among others in his beautiful Hymn of Jesus from 1917. This is typically a work which upon first listening makes you wonder why it's not better known (even though allegedly the work was quite succesful during its own time). There is, however, also something up with the continuity of Holst as a composer, as if technical challenges stimulated him more than creating a consistent style. Grove music Online quoted Holst's daughter Imogen regarding this remarkable phenomenon: 'As soon as he made his point, he stopped'.

After his study at the London Royal College, John Ireland developed first into a pianist, but he also studied composition with Stanford from 1897-1901. Equipped with a style founded on Brahms, he gradually changed his vision under influence of Debussy, Ravel and Stravinsky.
As a result, a series of lyrical piano works originated, followed by chamber music, including two violin sonatas (1909,1917) and two piano trio's (1906, 1917). Meanwhile, he had become an organist at St. Luke's in Chelsea (1904-1926) and he also went to teach at Royal College (1923-1939).
After the First World War, he wrote orchestral pieces like the symphonic rhapsody May Dun (1921), based on the English landscape and further the Piano Concerto (1930) and the Legend for piano and orchestra (1933).

Sergei Vasilievich Rachmaninov was a Russian pianist, composer, and conductor of the late-Romantic period, some of whose works are among the most popular in the classical repertoire.
Born into a musical family, Rachmaninov took up the piano at age four. He graduated from the Moscow Conservatory in 1892 and had composed several piano and orchestral pieces by this time. In 1897, following the critical reaction to his Symphony No. 1, Rachmaninoff entered a four-year depression and composed little until successful therapy allowed him to complete his enthusiastically received Piano Concerto No. 2 in 1901. After the Russian Revolution, Rachmaninov and his family left Russia and resided in the United States, first in New York City. Demanding piano concert tour schedules caused his output as composer to slow tremendously; between 1918 and 1943, he completed just six compositions, including Rhapsody on a Theme of Paganini, Symphony No. 3, and Symphonic Dances. In 1942, Rachmaninov moved to Beverly Hills, California. One month before his death from advanced melanoma, Rachmaninov acquired American citizenship.
Early influences of Tchaikovsky, Rimsky-Korsakov, Balakirev, Mussorgsky, and other Russian composers gave way to a personal style notable for its song-like melodicism, expressiveness and his use of rich orchestral colors.[3] The piano is featured prominently in Rachmaninov's compositional output, and through his own skills as a performer he explored the expressive possibilities of the instrument.
