Question: Information:  - Techno is a form of electronic dance music that emerged in Detroit, Michigan, in the United States during the mid-to-late 1980s. The first recorded use of the word "techno" in reference to a specific genre of music was in 1988. Many styles of techno now exist, but Detroit techno is seen as the foundation upon which a number of subgenres have been built.  - Classical music is art music produced or rooted in the traditions of Western music, including both liturgical (religious) and secular music. While a more accurate term is also used to refer to the period from 1750 to 1820 (the Classical period), this article is about the broad span of time from roughly the 11th century to the present day, which includes the Classical period and various other periods. The central norms of this tradition became codified between 1550 and 1900, which is known as the common-practice period. The major time divisions of Western art music are as follows:  European art music is largely distinguished from many other non-European and some popular musical forms by its system of staff notation, in use since about the 16th century. Western staff notation is used by composers to indicate to the performer the pitches (e.g., melodies, basslines, chords), tempo, meter and rhythms for a piece of music. This can leave less room for practices such as improvisation and "ad libitum" ornamentation, which are frequently heard in non-European art music and in popular-music styles such as jazz and blues. Another difference is that whereas most popular styles adopt the song (strophic) form, classical music has been noted for its development of highly sophisticated forms of instrumental music such as the concerto, symphony, sonata, and mixed vocal and instrumental styles such as opera which, since they are written down, can sustain larger forms and attain a high level of complexity.  - Tech house is a subgenre of house music that mixes elements of techno with house. The term "tech house" developed as a shorthand record store name for a category of electronic dance music that combined musical aspects of techno, such as "rugged basslines" and "steely beats," with the harmonies and grooves of progressive house. The music originally had a clean and minimal production style that was associated with techno from Detroit and the UK. In the mid to late 1990s a scene developed in England around club nights such as The Drop run by Mr.C & Plink Plonk, Heart & Soul, and Wiggle run by Terry Francis and Nathan Coles. Other DJs and artists associated with the sound at that time included Charles Webster, Bushwacka!, Cuartero, Dave Angel, Herbert, Funk D'Void, Ian O'Brien, Derrick Carter, and Stacey Pullen. By the late 90's London nightclub The End, owned by the former Shamen rapper Richard West (Mr C) and Layo Paskin, was considered the home of tech house in the UK. Tech house tracks are typically between 610 minutes in length.  - Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe. It includes 16 constituent states, covers an area of , and has a largely temperate seasonal climate. With about 82 million inhabitants, Germany is the most populous member state of the European Union. After the United States, it is the second most popular immigration destination in the world. Germany's capital and largest metropolis is Berlin. Other major cities include Hamburg, Munich, Cologne, Frankfurt, Stuttgart and Düsseldorf.  - Trance is a genre of electronic music that developed during the 1990s in Germany. It is characterized by a tempo lying between 125 and 150 beats per minute (BPM), repeating melodic phrases, and a musical form that distinctly builds tension and elements throughout a track often culminating in 1 to 2 "peaks" or "drops." Although trance is a genre of its own, it liberally incorporates influences from other musical styles such as techno, house, pop, chill-out, classical music, tech house, ambient, and film music.  - Matthias Paul, better known by his stage name Paul van Dyk (born 16 December 1971 in Eisenhüttenstadt, East Germany) is a German Grammy Award-winning DJ, record producer and musician. One of the first true superstar DJs, Paul van Dyk was the first artist to receive a Grammy Award nomination in the newly added category of Best Dance/Electronic album for his 2003 release "Reflections". He was named the World's number one DJ in both 2005 and 2006, something only few DJs have ever achieved. He was the first ever DJ to be named number one by "Mixmag" in 2005. By 2008, he had sold over 3 million albums worldwide.  - The Politics of Dancing 2 is an album of trance music mixed by Paul van Dyk as a sequel to his The Politics of Dancing .  - Mixmag is a British electronic dance and clubbing magazine, published in London, England. Launched in 1982, the magazine covers dance events, and reviews music and club nights.  - East Germany, formally the German Democratic Republic or GDR, was an Eastern Bloc state during the Cold War period. From 1949 to 1990, it administered the region of Germany that was occupied by Soviet forces at the end of World War IIthe Soviet Occupation Zone of the Potsdam Agreement, bounded on the east by the OderNeisse line. The Soviet zone surrounded West Berlin, but did not include it; as a result, West Berlin remained outside the jurisdiction of the GDR. The German Democratic Republic was established in the Soviet Zone, while the Federal Republic was established in the three western zones. East Germany was a satellite state of the Soviet Union. Soviet occupation authorities began transferring administrative responsibility to German communist leaders in 1948, and the GDR began to function as a state on 7 October 1949. Soviet forces, however, remained in the country throughout the Cold War. Until 1989, the GDR was governed by the Socialist Unity Party (SED), though other parties nominally participated in its alliance organisation, the National Front of Democratic Germany.   - Eisenhüttenstadt (literally "ironworks city" in German) is a town in the Oder-Spree district of the state of Brandenburg, Germany, on the border with Poland. It had a population of 32,214 as of 31 December 2008.    What entity does 'the politics of dancing 2' has the relation 'publication date' with?
