Information: - Folk music includes both traditional music and the genre that evolved from it during the 20th century folk revival. The term originated in the 19th century but is often applied to music that is older than that. Some types of folk music are also called world music. "Traditional folk music" has been defined in several ways: as music transmitted orally, music with unknown composers, or music performed by custom over a long period of time. It has been contrasted with commercial and classical styles. - 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. - Blues is a genre and musical form originated by African Americans in the Deep South of the United States around the end of the 19th century. The genre developed from roots in African musical traditions, African-American work songs and European-American folk music. Blues incorporated spirituals, work songs, field hollers, shouts, chants, and rhymed simple narrative ballads. The blues form, ubiquitous in jazz, rhythm and blues and rock and roll, is characterized by the call-and-response pattern, the blues scale and specific chord progressions, of which the twelve-bar blues is the most common. Blue notes (or "worried notes"), usually thirds or fifths flattened in pitch, are also an essential part of the sound. Blues shuffles or walking bass reinforce the trance-like rhythm and form a repetitive effect known as the groove. - Broadcasting House is the headquarters of the BBC, in Portland Place and Langham Place, London. The first radio broadcast was made on 15 March 1932, and the building was officially opened two months later, on 15 May. The main building is in Art Deco style, with a facing of Portland stone over a steel frame. It is a Grade II* listed building and includes the BBC Radio Theatre, where music and speech programmes are recorded in front of a studio audience, and lobby that was used as a location for filming the 1998 BBC television series "In the Red". - From September 1968 until the summer of 1980, English rock band Led Zeppelin were the world's most popular live music attraction, performing hundreds of sold-out concerts around the world. - The British Broadcasting Corporation (BBC) is a British public service broadcaster. It is headquartered at Broadcasting House in London, is the world's oldest national broadcasting organisation, and is the largest broadcaster in the world by number of employees, with over 20,950 staff in total, of whom 16,672 are in public sector broadcasting; including part-time, flexible as well as fixed contract staff, the total number is 35,402. - 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. - A concert is a live music performance in front of an audience. A recital is a concert by a soloist or small group which follows a program, such as featuring the works of a single composer (organ recital). A recitalist is a musician who gives frequent recitals. The invention of the solo piano recital has been attributed to Franz Liszt. - London is the capital and most populous city of England and the United Kingdom, as well as the most populous city proper in the European Union. Standing on the River Thames in the south east of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it "Londinium". London's ancient core, the City of London, largely retains its medieval boundaries. Since at least the 19th century, "London" has also referred to the metropolis around this core, historically split between Middlesex, Essex, Surrey, Kent, and Hertfordshire, which today largely makes up Greater London, governed by the Mayor of London and the London Assembly. - 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. - 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. - A progenitor is a person or thing from which others are descended or originate. For example, it is used to refer to the ancestor who started the line of a noble family. - '' The Girl I Love She Got Long Black Wavy Hair '' ( also known as '' The Girl I Love '' ) is a song performed by English rock band Led Zeppelin .
