Performance

A performance, in the performing arts, generally comprises an event in which a performer or group of performers present one or more works of art to an audience. Usually the performers participate in rehearsals beforehand. Afterwards audience members often applaud. After a performance, performance measurement sometimes occurs. Performance measurement is the process of collecting, analyzing and reporting information regarding the performance of an individual, group, organization, system or component.

The means of expressing appreciation can vary by culture. Chinese performers will clap with the audience at the end of a performance; the return applause signals "thank you" to the audience. In Japan, folk performing-arts performances commonly attract individuals who take photographs, sometimes getting up to the stage and within inches of performer's faces.

Sometimes the dividing line between performer and the audience may become blurred, as in the example of "participatory theatre" where audience members get involved in the production.

Computer performance

Computer performance is characterized by the amount of useful work accomplished by a computer system or computer network compared to the time and resources used. Depending on the context, high computer performance may involve one or more of the following:

Technical and non-technical definitions

The performance of any computer system can be evaluated in measurable, technical terms, using one or more of the metrics listed above. This way the performance can be

Whilst the above definition relates to a scientific, technical approach, the following definition given by Arnold Allen would be useful for a non-technical audience:

Performance (film)

Performance is a 1970 British crime drama film directed by Donald Cammell and Nicolas Roeg, written by Cammell and starring James Fox and Mick Jagger of The Rolling Stones, in his film acting debut. The film was produced in 1968 but not released until 1970.

Plot

Chas (James Fox) is a member of an East London gang led by Harry Flowers (Johnny Shannon); his specialty is intimidation through violence as he collects pay-offs for Flowers. He is very good at his job, and has a reputation for liking it. His sexual liaisons are casual and rough. When Flowers decides to take over a betting shop, owned by Joey Maddocks (Anthony Valentine), he forbids Chas to get involved, as he feels Chas's complicated personal history with Maddocks (which is at least partly gay) may lead to trouble. Chas is angry about this and later humiliates Maddocks, who retaliates by wrecking Chas's apartment and attacking Chas. Chas shoots him, packs a suitcase and runs from the scene.

When Flowers makes it clear that he has no intention of offering protection to Chas but instead wants him eliminated, Chas decides to head for the countryside to hide but instead winds up hiding out in London, requesting that Tony (a trusted friend he refers to as 'Uncle') helps him get out of the country. He assumes a new name, Johnny Dean, and appears at the house of Turner (Mick Jagger), makes a clumsy attempt to ingratiate himself with Pherber (Anita Pallenberg), one of the female inhabitants, and moves in. Turner is a reclusive, eccentric former rock star who has "lost his demon", and who lives there with his female friends Pherber and Lucy (Michele Breton), with whom he enjoys a non-possessive and bisexual ménage à trois, and their child maid Lorraine (Laraine Wickens).

Landscape (band)

Landscape was an English Synthpop band, best known for the 1981 hits "Einstein A Go-Go" and "Norman Bates." Formed in London in 1974, the band toured constantly during the mid-to-late-1970s, playing rock, punk, and jazz venues and releasing two instrumental EPs on its own Event Horizon label. The group began experimenting with computer-programmed music and electronic drums in the late 1970s and early 1980s, making records in the emerging genre of synthpop.

Formation

Landscape was composed of Richard James Burgess (vocals, drums), Christopher Heaton (keyboards), Andy Pask (bass), Peter Thoms (trombone, keyboards), and John Walters (keyboards, woodwinds). The band built a following through live performances and touring before releasing their debut album Landscape in 1980. Their next album in 1981, From the Tea-Rooms of Mars...to the Hell-Holes of Uranus led to the Top Five U.K. hit "Einstein A-Go-Go." Their third album in 1982, Manhattan Boogie-Woogie was well received as a dance album. After release of this album, Heaton and Thoms left the band.

Landscape painting

Landscape painting, also known as landscape art, is the depiction in art of landscapes – natural scenery such as mountains, valleys, trees, rivers, and forests, especially where the main subject is a wide view – with its elements arranged into a coherent composition. In other works landscape backgrounds for figures can still form an important part of the work. Sky is almost always included in the view, and weather is often an element of the composition. Detailed landscapes as a distinct subject are not found in all artistic traditions, and develop when there is already a sophisticated tradition of representing other subjects. The two main traditions spring from Western painting and Chinese art, going back well over a thousand years in both cases. The recognition of a spiritual element in landscape art is present from its beginnings in East Asian art, drawing on Daoism and other philosophical traditions, but in the West only becomes explicit with Romanticism.

Landscape (horse)

Landscape (1813–1834) was a British Thoroughbred racehorse and broodmare who won the classic Oaks Stakes at Epsom Downs Racecourse in 1816. The filly's entire racing career consisted of one run in 1815 followed by three races in the space of thirteen days in June 1816. After winning the Oaks on her second racecourse appearance, she finished first and second in races at Ascot. Already pregnant at the time of her classic success, Landscape was retired from racing after Ascot and produced her first foal in the following spring.

Background

Landscape was a bay mare bred by her owner General John Leveson Gower who had won the Oaks with Maid of Orleans in 1809. Her sire, Rubens was a successful racehorse, who at the time of Landscape's conception was covering mares at Wheeler's Farm near Wokingham in Berkshire at a fee of 15 guineas. He sired two other classic winning fillies in Pastille, who won the 2000 Guineas and Oaks in 1816 and Whizgig, who won the 1000 Guineas in the same year. Rubens was champion sire in 1815, 1821 and 1822. Landscape's dam Housemaid (also known as Iris) produced several other good winners including Raphael, who finished second to Whisker in the 1815 Epsom Derby and Rainbow, who became a successful stallion in France.
