Information:  - John Henry Bonham (31 May 1948  25 September 1980) was an English drummer, musician and songwriter, best known as the drummer of Led Zeppelin. Bonham was esteemed for his speed, power, fast bass-drumming, distinctive sound, and "feel" for the groove. He is considered by some publications to be one of the greatest drummers in rock.  - The gittern was a relatively small gut strung round-backed instrument that first appears in literature and pictorial representation during the 13th century in Western Europe (Iberian Peninsula, Italy, France, England). It is usually depicted played with a quill plectrum, as we can see clearly beginning in manuscript illuminations from the thirteenth century.  It was also called the guitarra in Spain, guiterne or guiterre in France, the chitarra in Italy and quintern in Germany. A popular instrument with court musicians, minstrels, and amateurs, the gittern is considered ancestral to the modern guitar; possibly other instruments like the mandore and gallichon.  - In Through the Out Door is the eighth studio album by the English rock band Led Zeppelin, and their final album of entirely new material. It was recorded over a three-week period in November and December 1978 at ABBA's Polar Studios in Stockholm, Sweden, and released by Swan Song Records on 15 August 1979. "In Through the Out Door" was the band's eighth and final studio release to reach the top of the charts in America, and was the last released by the band before the death of drummer John Bonham in 1980.  - ABBA (stylised ) are a Swedish pop group formed in Stockholm in 1972 by Agnetha Fältskog, Björn Ulvaeus, Benny Andersson, and Anni-Frid Lyngstad. They became one of the most commercially successful acts in the history of popular music, topping the charts worldwide from 1974 to 1982. ABBA won the Eurovision Song Contest 1974 at The Dome in Brighton, UK, giving Sweden its first triumph in the contest, and are the most successful group to ever take part in the competition.  - Swan Song Records was a record label launched by the English rock band Led Zeppelin on 10 May 1974. It was overseen by Led Zeppelin's manager Peter Grant and was a vehicle for the band to promote its own products as well as sign artists who found it difficult to win contracts with other major labels. The decision to launch the label came after Led Zeppelin's five-year contract with Atlantic Records expired at the end of 1973, although Atlantic ultimately distributed the label's product.  - Led Zeppelin were an English rock band formed in London in 1968. The group consisted of guitarist Jimmy Page, singer Robert Plant, bassist and keyboardist John Paul Jones, and drummer John Bonham. The band's heavy, guitar-driven sound, rooted in blues and psychedelia on their early albums, has earned them recognition as one of the progenitors of heavy metal, though their unique style drew from a wide variety of influences, including folk music.  - The guitar is a musical instrument classified as a string instrument with anywhere from four to 18 strings, usually having six. The sound is projected either acoustically, using a hollow wooden or plastic and wood box (for an acoustic guitar), or through electrical amplifier and a speaker (for an electric guitar). It is typically played by strumming or plucking the strings with the fingers, thumb and/or fingernails of the right hand or with a pick while fretting (or pressing against the frets) the strings with the fingers of the left hand. The guitar is a type of chordophone, traditionally constructed from wood and strung with either gut, nylon or steel strings and distinguished from other chordophones by its construction and tuning. The modern guitar was preceded by the gittern, the vihuela, the four-course Renaissance guitar, and the five-course baroque guitar, all of which contributed to the development of the modern six-string instrument.  - British English is the English language as spoken and written in the United Kingdom or, more broadly, throughout the British Isles. Slight regional variations exist in formal, written English in the United Kingdom. For example, the adjective "wee" is almost exclusively used in parts of Scotland and Northern Ireland, and occasionally Yorkshire, whereas "little" is predominant elsewhere. Nevertheless, there is a meaningful degree of uniformity in "written" English within the United Kingdom, and this could be described by the term "British English". The forms of "spoken" English, however, vary considerably more than in most other areas of the world where English is spoken, so a uniform concept of British English is more difficult to apply to the spoken language. According to Tom McArthur in the "Oxford Guide to World English", British English shares "all the ambiguities and tensions in the word "British" and as a result can be used and interpreted in two ways, more broadly or more narrowly, within a range of blurring and ambiguity."  - `` Carouselambra '' is the fifth track on Led Zeppelin 's 1979 album In Through the Out Door . The name Carouselambra is a reference to the first section of the song sounding similar to carousel music . It is the second - longest song the band recorded in the studio ( after `` In My Time of Dying '' ) , clocking in at more than 10 minutes in length . It 's also a very unusual song for the band , as Jimmy Page 's guitar work is pushed almost to the background , while John Paul Jones dominates with heavy use of synthesizers .  - Polar Studios was a recording studio in Stockholm, Sweden, which operated from 1978 through 2004. The studio was formed by ABBA musicians Björn Ulvaeus and Benny Andersson and the band's manager Stig Anderson, owner of the Polar Music recording label.  - A carousel (American English: from French "carrousel" and Italian "carosello"), roundabout (British English), or merry-go-round, is an amusement ride consisting of a rotating circular platform with seats for riders. The "seats" are traditionally in the form of rows of wooden horses or other animals mounted on posts, many of which are moved up and down by gears to simulate galloping, to the accompaniment of looped circus music. This leads to one of the alternative American names, the galloper. Other popular names are jumper, horseabout and flying horses.  - 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.  - The Renaissance was a period in European history, from the 14th to the 17th century, regarded as the cultural bridge between the Middle Ages and modern history. It started as a cultural movement in Italy in the Late Medieval period and later spread to the rest of Europe, marking the beginning of the Early Modern Age.  - Robert Anthony Plant, (born 20 August 1948) is an English musician, singer, and songwriter best known as the lead singer and lyricist of the rock band Led Zeppelin. A powerful and wide vocal range (particularly evident in his high-pitched vocals) has given him a successful solo career spanning over 30 years. Plant is regarded as one of the greatest singers in the history of rock and roll; he has influenced fellow rock singers such as Freddie Mercury, Axl Rose and Chris Cornell. In 2006, Heavy Metal magazine "Hit Parader" named Plant the "Greatest Metal Vocalist of All Time". In 2009, Plant was voted "the greatest voice in rock" in a poll conducted by "Planet Rock". In 2008, "Rolling Stone" editors ranked him number 15 on their list of the 100 best singers of all time. In 2011, "Rolling Stone" readers ranked Plant the greatest of all lead singers.  - American English (variously abbreviated AmE, AE, AmEng, USEng, en-US), also called United States English or U.S. English, is the set of varieties of the English language native to the United States. English is the most widely spoken language in the United States and is the common language used by the federal government, considered the "de facto" language of the country because of its widespread use. English has been given official status by 32 of the 50 state governments. As an example, while both Spanish and English have equivalent status in the local courts of Puerto Rico. Under federal law, English is the official language for any matters being referred to the United States district court for the territory.  - Sweden, officially the Kingdom of Sweden (Swedish: ), is a Scandinavian country in Northern Europe. It borders Norway to the west and Finland to the east, and is connected to Denmark in the southwest by a bridge-tunnel across the Öresund. At , Sweden is the third-largest country in the European Union by area, with a total population of 10.0 million. Sweden consequently has a low population density of , with the highest concentration in the southern half of the country. Approximately 85% of the population lives in urban areas.  - Circus music (also known as carnival music) is any sort of music that is played to accompany a circus, and also music written that emulates its general style. Popular music would also often get arranged for the circus band, as well as waltzes, foxtrots and other dances.  - James Patrick "Jimmy" Page, (born 9 January 1944) is an English musician, songwriter, and record producer who achieved international success as the guitarist and founder of the rock band Led Zeppelin.  - A Zeppelin was a type of rigid airship named after the German Count Ferdinand von Zeppelin who pioneered rigid airship development at the beginning of the 20th century. Zeppelin's notions were first formulated in 1874 and developed in detail in 1893. They were patented in Germany in 1895 and in the United States in 1899. After the outstanding success of the Zeppelin design, the word "zeppelin" came to be commonly used to refer to all rigid airships. Zeppelins were first flown commercially in 1910 by Deutsche Luftschiffahrts-AG (DELAG), the world's first airline in revenue service. By mid-1914, DELAG had carried over 10,000 fare-paying passengers on over 1,500 flights. During World War I the German military made extensive use of Zeppelins as bombers and scouts, killing over 500 people in bombing raids in Britain.
