Arbour Zena is an album composed by American pianist Keith Jarrett featuring saxophonist Jan Garbarek, bassist Charlie Haden and the Stuttgart Radio Symphony Orchestra conducted by Mladen Gutesha which was released on the ECM label in 1975.

The Allmusic review by Richard S. Ginell awarded the album 3 stars and states "although this music can be attractive in small doses, the lack of tempo or texture contrasts over long stretches of time — particularly the nearly 28-minute "Mirrors" — which can be annoying if you're not in the right blissful mood".

Keith Jarrett (born May 8, 1945, in Allentown, Pennsylvania) is an American pianist and composer who performs both jazz and classical music.

Jarrett started his career with Art Blakey, moving on to play with Charles Lloyd and Miles Davis. Since the early 1970s he has enjoyed a great deal of success in jazz, jazz fusion, and classical music; as a group leader and a solo performer. His improvisations draw not only from the traditions of jazz, but from other genres as well, especially Western classical music, gospel, blues, and ethnic folk music.

In 2003, Jarrett received the Polar Music Prize, the first (and to this day only) recipient not to share the prize with a co-recipient, and in 2004 he received the Léonie Sonning Music Prize.

In 2008, he was inducted into the Down Beat Hall of Fame in the magazine's 73rd Annual Readers' Poll.

Jarrett grew up in suburban Allentown, Pennsylvania, with significant early exposure to music. He possessed absolute pitch, and he displayed prodigious musical talents as a young child. He began piano lessons just before his third birthday, and at age five he appeared on a TV talent program hosted by the swing bandleader Paul Whiteman. The young Jarrett gave his first formal piano recital at the age of seven, playing works by composers including Mozart, Bach, Beethoven, and Saint-Saëns, and ending with two of his own compositions. Encouraged especially by his mother, Jarrett took intensive classical piano lessons with a series of teachers, including Eleanor Sokoloff of the Curtis Institute.

LaDonna Adrian Gaines (December 31, 1948 – May 17, 2012), known by the stage name Donna Summer, was an American singer and songwriter who gained prominence during the disco era of the late 1970s. She had a mezzo-soprano vocal range, and was a five-time Grammy Award winner. Summer was the first artist to have three consecutive double albums reach number one on the United States Billboard chart, and she also charted four number-one singles in the United States within a 13-month period.

Born into a devoutly Christian lower middle class African American family in Boston, Massachusetts, Summer first became involved with singing through church choir groups before joining a number of bands influenced by the Motown Sound. Influenced by the counterculture of the 1960s, she became the front singer of a psychedelic rock band named Crow and moved to New York City. Joining a touring version of the musical Hair, she spent several years living in West Germany, where she married Helmut Sommer, whose surname she adopted as her stage name.

Sir Elton Hercules John, CBE (born Reginald Kenneth Dwight on 25 March 1947) is an English rock singer-songwriter, composer, pianist and occasional actor. He has worked with lyricist Bernie Taupin as his songwriter partner since 1967; they have collaborated on more than 30 albums to date.

In his four-decade career John has sold more than 250 million records, making him one of the most successful artists of all time. His single "Candle in the Wind 1997" has sold over 33 million copies worldwide, and is the best selling single in Billboard history. He has more than 50 Top 40 hits, including seven consecutive No. 1 US albums, 56 Top 40 singles, 16 Top 10, four No. 2 hits, and nine No. 1 hits. He has won six Grammy Awards, four Brit Awards, an Academy Award, a Golden Globe Award and a Tony Award. In 2004, Rolling Stone ranked him Number 49 on its list of the 100 greatest artists of all time.

John was inducted into the Rock and Roll Hall of Fame in 1994. Having been named a Commander of the Order of the British Empire in 1996, John received a knighthood from Queen Elizabeth II for "services to music and charitable services" in 1998.

Jan Garbarek (born 4 March 1947) is a Norwegian tenor and soprano saxophonist, active in the jazz, classical, and world music genres. Garbarek was born in Mysen, Norway, the only child of a former Polish prisoner of war Czesław Garbarek and a Norwegian farmer's daughter. Effectively stateless until the age of seven (there was no automatic grant of citizenship in Norway at that time) Garbarek grew up in Oslo. At 21, he married Vigdis. His daughter Anja Garbarek is also a musician.

Garbarek's sound is one of the hallmarks of the ECM Records label, which has released virtually all of his recordings. His style incorporates a sharp-edged tone, long, keening, sustained notes, and generous use of silence. He began his recording career in the late 1960s, notably featuring on recordings by the American jazz composer George Russell (such as Othello Ballet Suite and Electronic Sonata for Souls Loved by Nature). If he had initially appeared as a devotee of Albert Ayler and Peter Brötzmann, by 1973 he had turned his back on the harsh dissonances of avant-garde jazz, retaining only his tone from his previous approach. Garbarek gained wider recognition through his work with pianist Keith Jarrett's European Quartet which released the albums Belonging (1974), My Song (1977) and the live recordings Personal Mountains (1979), and Nude Ants (1979). He was also a featured soloist on Jarrett's orchestral works Luminessence (1974) and Arbour Zena (1975)
