Background: 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.
Context: Haden often said that he moved to Los Angeles in 1957 in search of pianist Hampton Hawes. He turned down a full scholarship at Oberlin College, which did not have an established jazz program at the time, to attend Westlake College of Music in Los Angeles. His first recordings were made that year with Paul Bley, with whom he worked until 1959. He also played with Art Pepper for four weeks in 1957, and from 1958 to 1959, with Hampton Hawes whom he met through his friendship with bassist Red Mitchell, For a time, he shared an apartment with the bassist Scott LaFaro.  In May 1959, he recorded his first album with the Ornette Coleman Quartet, the seminal The Shape of Jazz to Come. Haden's folk-influenced style complemented Coleman's microtonal, Texas blues elements. Later that year, the Quartet moved to New York City and secured an extended booking at the avant-garde Five Spot Cafe. This residency lasted six weeks and represented the beginnings of their unique, free and avant-garde jazz. Ornette's quartet played everything by ear, as Haden explained: "At first when we were playing and improvising, we kind of followed the pattern of the song, sometimes. Then, when we got to New York, Ornette wasn't playing on the song patterns, like the bridge and the interlude and stuff like that. He would just play. And that's when I started just following him and playing the chord changes that he was playing: on-the-spot new chord structures made up according to how he felt at any given moment."  In 1960, addiction to narcotics caused him to leave Coleman's band. He went to self-help rehabilitation in September 1963 at Synanon houses in Santa Monica, California and San Francisco, California. It was during the time he was at Synanon House that he met his first wife, Ellen David. They moved to New York City's Upper West Side where their four children were born: their son, Josh, in 1968, and in 1971, their triplet daughters Petra, Rachel and Tanya. They separated in 1975 and, subsequently, divorced.
