A concert is a live performance (typically of music) before an audience. The performance may be by a single musician, sometimes then called a recital, or by a musical ensemble, such as an orchestra, a choir, or a musical band. Concerts are held in a wide variety and size of settings, from private houses and small nightclubs, dedicated concert halls, entertainment centres and parks to large multipurpose buildings, and even sports stadiums. Indoor concerts held in the largest venues are sometimes called "arena concerts". Regardless of the venue, musicians usually perform on a stage. Concerts often require live event support with professional audio equipment. Before recorded music, concerts would provide the only opportunity one would generally have to hear musicians play. Informal names for a concert include "show" and "gig".

The nature of a concert will vary by musical genre and the individual performers. Concerts by a small jazz combo or small bluegrass band may have the same order of program, mood, and volume, but vary in music and dress. In a similar way, a particular musician, band, or genre of music might attract concert attendees with similar dress, hairstyle, and behavior. For example, the hippies of the 60s often toted long hair (sometimes in dread lock form), sandals and inexpensive clothing made of natural fibers. The regular attendees to a concert venue might also have a recognizable style, comprising that venue's "scene".

Philip David Charles "Phil" Collins, LVO (born 30 January 1951) is an English singer-songwriter, drummer, pianist and actor best known as a drummer and vocalist for British progressive rock group Genesis and as a solo artist.

Collins sang the lead vocals on several chart hits in the United Kingdom and the United States between 1975 and 2010, either as a solo artist or with Genesis. His singles, sometimes dealing with lost love, ranged from the drum-heavy "In the Air Tonight", dance pop of "Sussudio", piano-driven "Against All Odds", to the political statements of "Another Day in Paradise".

Collins's professional music career began as a drummer, originally in a band called The Real Thing with Andrea Bertorelli, who later became his first wife. Collins played drums and shared lead vocals (with Brian Chatton) in Flaming Youth which recorded one album, (Ark II). In 1970, he took over drums for Genesis, which had already recorded two albums. In Genesis, Collins originally supplied backing vocals for front man Peter Gabriel, singing lead on only two songs: "For Absent Friends" from 1971's Nursery Cryme album and "More Fool Me" from Selling England by the Pound, which was released in 1973. Following Gabriel's departure in 1975, Collins became the group's lead singer.

Jean Michel André Jarre (born 24 August 1948 in Lyon) is a French composer, performer and music producer. He is a pioneer in the electronic, ambient and New Age genres, and known as an organiser of outdoor spectacles of his music featuring lights, laser displays, and fireworks.

Jarre was raised in Lyon by his mother and grandparents, and trained on the piano. From an early age he was introduced to a variety of art forms, including those of street performers, jazz musicians, and the artist Pierre Soulages. He played guitar in a band, but his musical style was perhaps most heavily influenced by Pierre Schaeffer, a pioneer of musique concrète at the Groupe de Recherches Musicales.

His first mainstream success was the 1976 album Oxygène. Recorded in a makeshift studio at his home, the album sold an estimated 12 million copies. Oxygène was followed in 1978 by Équinoxe, and in 1979 Jarre performed to a record-breaking audience of more than a million people at the Place de la Concorde, a record he has since broken three times. More albums were to follow, but his 1979 concert served as a blueprint for his future performances around the world. Several of his albums have been released to coincide with large-scale outdoor events, and he is now perhaps as well known as a performer as a musician.

David Jon Gilmour,CBE (born 6 March 1946) is an English rock musician and multi-instrumentalist who is best known as the guitarist, one of the lead singers and main songwriters in the progressive rock band Pink Floyd.

In addition to his work with Pink Floyd, Gilmour has worked as a producer for a variety of artists, and has enjoyed a successful career as a solo artist. Gilmour has been actively involved with many charities over the course of his career.

In 2003, he was appointed CBE for his charity work and was awarded with the Outstanding Contribution title at the 2008 Q Awards. In 2011, Rolling Stone Magazine ranked him number 14 in their list of the greatest guitarists of all time.

Gilmour was born in Cambridge, England. His father, Douglas Gilmour, was a senior lecturer in zoology at the University of Cambridge and his mother, Sylvia (née Wilson), was a teacher and film editor who raised her family at Grantchester Meadows, later immortalised by a Roger Waters song on Pink Floyd's Ummagumma. He has a younger brother who is also a musician.
