Information: - Gary Davies (born 13 December 1954, Manchester, England) is a British broadcaster. During the 1980s and early 1990s he was a BBC Radio 1 disc jockey and a regular presenter of "Top of the Pops". - The theremin (originally known as the therphone/etherphone, thereminophone or termenvox/thereminvox) is an early electronic musical instrument controlled without physical contact by the thereminist (performer). It is named after the Westernized name of its Russian inventor, Leon Theremin (e), who patented the device in 1928. - A synthesizer (often abbreviated as synth, also spelled synthesiser) is an electronic musical instrument that generates electric signals that are converted to sound through instrument amplifiers and loudspeakers or headphones. Synthesizers may either imitate instruments like piano, Hammond organ, flute, vocals; natural sounds like ocean waves, etc.; or generate new electronic timbres. They are often played with a musical keyboard, but they can be controlled via a variety of other input devices, including music sequencers, instrument controllers, fingerboards, guitar synthesizers, wind controllers, and electronic drums. Synthesizers without built-in controllers are often called "sound modules", and are controlled via MIDI or CV/Gate using a controller device, often a MIDI keyboard or other controller. - ZTT Records is a British record label founded in 1983 by "NME" journalist Paul Morley, record producer Trevor Horn, and businesswoman Jill Sinclair. The label's name was also printed as "Zang Tumb Tuum" and "Zang Tuum Tumb" on various releases. - Graham Massey (born 4 August 1960 in Manchester) was a member of experimental jazz rock group Biting Tongues once signed to Factory Records. By 1988, he was a founding member of the British band, 808 State, formed in Manchester, England which by 1989 became the focus of his work and resulted in the demise of Biting Tongues. Originally a hip hop group called Hit Squad Manchester, they shifted to an acid house sound, recording their debut album, "Newbuild" in 1988 under the new name 808 State. - A computer is a device that can be instructed to carry out an arbitrary set of arithmetic or logical operations automatically. The ability of computers to follow a sequence of operations, called a "program", make computers very flexible and useful. Such computers are used as control systems for a very wide variety of industrial and consumer devices. This includes simple special purpose devices like microwave ovens and remote controls, factory devices such as industrial robots and computer assisted design, but also in general purpose devices like personal computers and mobile devices such as smartphones. The Internet is run on computers and it connects millions of other computers. - The Telharmonium (also known as the Dynamophone) was an early electrical organ, developed by Thaddeus Cahill circa 1896 and patented in 1897. The electrical signal from the Telharmonium was transmitted over wires; it was heard on the receiving end by means of "horn" speakers. - opti buk is a DVD by electronic music group 808 State which was released in 2002 . Also included was a bonus album , State to State 2 . The DVD has been deleted , and only archive copies may be available . The name of the DVD is derived from optical ( opti ) and book ( buk ) . - 808 State are an English electronic music group, formed in 1987 in Manchester, taking their name from the Roland TR-808 drum machine. They were formed by Graham Massey, Martin Price and Gerald Simpson, and they released their debut album, "Newbuild", in September 1988. The band secured commercial success in 1989, when their song "Pacific State" was picked up by BBC Radio 1 DJ Gary Davies. - The Roland TR-808 Rhythm Composer, often referred to simply as the 808, is a drum machine introduced by the Roland Corporation in 1980 and discontinued in 1983. It was one of the earliest programmable drum machines, with which users could create their own rhythms rather than having to use presets. - BBC Radio 1 is a British radio station operated by the British Broadcasting Corporation which also broadcasts internationally, specialising in modern and current popular music and chart hits throughout the day. Radio 1 provides alternative genres after 7:00 pm, including electronic dance, hip hop, rock, indie or interviews. It is aimed primarily at the 1529 age group, although the average age of the UK audience in 2008 was 33. BBC Radio 1 started 24-hour broadcasting on 1 May 1991. - Manchester is a major city and metropolitan borough in Greater Manchester, England, with a population of 514,414 . It lies within the United Kingdom's second-most populous urban area, with a population of 2.55 million. Manchester is fringed by the Cheshire Plain to the south, the Pennines to the north and east and an arc of towns with which it forms a continuous conurbation. The local authority is Manchester City Council. - An electronic musical instrument is a musical instrument that produces sound using electronics. Such an instrument sounds by outputting an electrical audio signal that ultimately drives a loudspeaker. - A drum machine is an electronic musical instrument designed to imitate the sound of drums, cymbals, other percussion instruments, and often basslines. Drum machines are most commonly associated with electronic music genres such as house music, but are also used in many other genres. - Electronic music is music that employs electronic musical instruments and electronic music technology in its production, an electronic musician being a musician who composes and/or performs such music. In general, a distinction can be made between sound produced using electromechanical means and that produced using electronic technology. Examples of electromechanical sound producing devices include the telharmonium, Hammond organ, and the electric guitar. Purely electronic sound production can be achieved using devices such as the theremin, sound synthesizer, and computer. - An electric guitar is a fretted string instrument that uses a pickup to convert the vibration of its stringswhich are typically made of steel, and which occurs when a guitarist strums, plucks or fingerpicks the stringsinto electrical signals. The vibrations of the strings are sensed by a pickup, of which the most common type is the magnetic pickup, which uses the principle of direct electromagnetic induction. The signal generated by an electric guitar is too weak to drive a loudspeaker, so it is plugged into a guitar amplifier before being sent to a loudspeaker, which makes a sound loud enough to hear. The output of an electric guitar is an electric signal, and the signal can easily be altered by electronic circuits to add "color" to the sound or change the sound. Often the signal is modified using effects such as reverb and distortion and "overdrive", with the latter being a key element of the sound of the electric guitar as it is used in blues and rock music. - State to State 2 is an compilation album by English electronic music group 808 State, which was released in 2002 by ZTT Records. It was only available with the "opti buk" DVD. - The Hammond organ is an electric organ, invented by Laurens Hammond and John M. Hanert and first manufactured in 1935. Various models have been produced, most of which use sliding drawbars to create a variety of sounds. Until 1975, Hammond organs generated sound by creating an electric current from rotating a metal tonewheel near an electromagnetic pickup, and then strengthening the signal with an amplifier so that it can drive a speaker cabinet. Around two million Hammond organs have been manufactured. The organ is commonly used with, and associated with, the Leslie speaker.
