フリー・ジャズ
Free jazz was unpopular and didn't sell well. It was viewed as a musical, political, and social backlash to the structure of jazz and of American society at the time. "For some performers the style was loosely linked to the Black Power movement in the USA, partly because of the radical political outlook of some of its practitioners and advocates (e.g., Archie Shepp and LeRoi Jones – later known as Amiri Baraka) and partly owing to the explosive, expressionistic nature of the music itself". Due to the lack of commercial success of the free jazz music as well as the racial issues, like the Civil Rights Movement, many American free jazz musicians began touring the European continent, playing and spreading their new avant-garde style throughout Europe. Jazz musicians like Ornette Coleman, Albert Ayler, Don Cherry, Bud Powell, Don Byas traveled and performed throughout Europe. In contrast to the lack of commercial success in America, many American free jazz musicians experienced both commercial success and acceptance in Europe, leading to tours of Europe and extended residencies. "A number of jazz musicians migrated to other parts of the world, where they received an opposite response, being considered the ultimate expression of high culture. Thus, many of them remained in exile, and they enjoyed unparalleled success in France, Germany, Japan, Scandinavia, and the Netherlands after the world wars".
