Charles Edward "Charlie" Haden (August 6, 1937 - July 11, 2014) was an American jazz double bass player, bandleader, composer and educator known for his deep, warm sound, and whose career spanned more than fifty years. In the late 1950s, Haden was an original member of the ground-breaking Ornette Coleman Quartet. Haden revolutionized the harmonic concept of bass playing in jazz. About him, German musicologist Joachim-Ernst Berendt commented, "His ability to create serendipitous harmonies by improvising melodic responses to Coleman's free-form solos (rather than sticking to predetermined harmonies) was both radical and mesmerizing.

In 1984 Haden met the singer and former actress Ruth Cameron. They married in New York City, and throughout their marriage, Ruth managed Haden's career as well as co-producing many albums and projects with him.  In 1986, Haden formed his band Quartet West at Ruth's suggestion. The original quartet consisted of Ernie Watts on sax, Alan Broadbent on piano, and long-time collaborator, Billy Higgins, on drums. Higgins was later replaced by Larance Marble. When Marable became too ill to perform, drummer Rodney Green was added to the band. In addition to original compositions by Haden and Broadbent, their repertoire also included 1940s pop ballads which they played a noir-infused, bop-oriented style. A brief collaboration with tenor saxophonist Joe Henderson and drummer Al Foster showcased Haden's playing in a more hard-driving jazz context.  In 1989, Haden inaugurated the "Invitation" series at the Montreal Jazz Festival. With different musicians he selected, they performed in concert for eight consecutive nights of the festival. Each of these events was recorded, and most have been released in the series, The Montreal Tapes.  Duets: Haden performing in duets as he loved the intimacy the format provided. In 1995, Haden released Steal Away: Spirituals, Hymns and Folk Songs with pianist Hank Jones, an album based on traditional spirituals and folk songs. Haden both played on and produced the album. In late 1996, he collaborated with guitarist Pat Metheny on the album Beyond the Missouri Sky (Short Stories), exploring the music that influenced them in their childhood experiences in, respectively southwest Iowa and northwest Missouri, with what Haden called "contemporary impressionistic Americana". Haden was awarded his first Grammy award for the album, for Best Jazz Instrumental Performance.  In 1997, classical composer Gavin Bryars wrote By the Vaar, an extended adagio for Haden. Instrumentation included strings, bass clarinet and percussion. The piece was recorded with the English Chamber Orchestra, on the album Farewell to Philosophy. It is a synthesis of jazz and classical chamber music, featuring resonant pizzicato notes and gut strings in imitation of Haden's bass sound.
