Weather Report

Weather Report was an American jazz fusion band of the 1970s and early 1980s. The band was co-led by the Austrian-born keyboard player Joe Zawinul and the American saxophonist Wayne Shorter (and, initially, by Czech bass player Miroslav Vitouš). Other prominent members at various points in the band's lifespan included Jaco Pastorius, Peter Erskine, Alex Acuña, Alphonso Johnson, Victor Bailey, Airto Moreira and Chester Thompson.

Alongside Miles Davis's electric bands, The Mahavishnu Orchestra, Return to Forever, and Headhunters, Weather Report is considered to be one of the pre-eminent early jazz fusion bands. As a continuous working unit, Weather Report outlasted all of its contemporaries despite (or perhaps because of) frequent changes of personnel, with a career lasting sixteen years between 1970 and 1986.

Musical style

Over a sixteen-year career Weather Report's music explored various areas, centered on jazz (including both the "free" and "Latin" varieties) but also including various elements of art music, ethnic music, R&B, funk and rock. While their work was often categorized as "jazz fusion", the band members themselves generally rejected the term.

Joe Zawinul

Josef Erich "Joe" Zawinul (July 7, 1932 – September 11, 2007) was an Austrian jazz keyboardist and composer.

First coming to prominence with saxophonist Cannonball Adderley, Zawinul went on to play with trumpeter Miles Davis, and to become one of the creators of jazz fusion, an innovative musical genre that combined jazz with elements of rock and world music. Later, Zawinul co-founded the groups Weather Report and the world fusion music-oriented Zawinul Syndicate. Additionally, he made pioneering use of electric piano and synthesizers. Zawinul was named "Best Electric Keyboardist" 28 times by the readers of Down Beat magazine.

A number of prominent musical artists have honored Zawinul with compositions, including Brian Eno's instrumental "Zawinul/Lava", John McLaughlin's instrumental "Jozy", Warren Cuccurullo's "Hey Zawinul", Bob Baldwin's "Joe Zawinul", Chucho Valdés's "Zawinul's Mambo", Biréli Lagrène's instrumental "Josef" and Toninho Horta's instrumental "Balada para Zawinul". Zawinul's playing style was often dominated by quirky melodic improvisations – traversing bebop, ethnic and pop styles – combined with sparse but rhythmic playing of big-band sounding chords or bass lines. In Weather Report, he often employed a vocoder as well as pre-recorded sounds played (i.e. filtered and transposed) through a synthesizer, a method or technique called sampling, creating a very distinctive synthesis of jazz harmonies and "noise" ("using all the sounds the world generates").

Black market

A black market, underground economy, or shadow economy is a market in which goods or services are traded illegally. The key distinction of a black market trade is that the transaction itself is illegal. The goods or services themselves may or may not be illegal to own, or to trade through other, legal channels. Because the transactions are illegal, the market itself is forced to operate outside the formal economy that is supported by the established state power. Common motives for operating in black markets are to trade contraband, avoid taxes and regulations, or skirt price controls or rationing. Typically the totality of such activity is referred to with the definite article as a complement to the official economies, by market for such goods and services, e.g. "the black market in bush meat".

The black market is distinct from the grey market, in which commodities are distributed through channels which, while legal, are unofficial, unauthorized, or unintended by the original manufacturer, and the white market.

Weather

Weather is the state of the atmosphere, to the degree that it is hot or cold, wet or dry, calm or stormy, clear or cloudy. Most weather phenomena occur in the troposphere, just below the stratosphere. Weather refers to day-to-day temperature and precipitation activity, whereas climate is the term for the statistics of atmospheric conditions over longer periods of time. When used without qualification, "weather" is generally understood to mean the weather of Earth.

Weather is driven by air pressure, temperature and moisture differences between one place and another. These differences can occur due to the sun's angle at any particular spot, which varies by latitude from the tropics. The strong temperature contrast between polar and tropical air gives rise to the jet stream. Weather systems in the mid-latitudes, such as extratropical cyclones, are caused by instabilities of the jet stream flow. Because the Earth's axis is tilted relative to its orbital plane, sunlight is incident at different angles at different times of the year. On Earth's surface, temperatures usually range ±40 °C (−40 °F to 100 °F) annually. Over thousands of years, changes in Earth's orbit can affect the amount and distribution of solar energy received by the Earth, thus influencing long-term climate and global climate change.
