L’Orchestra, a cooperative established in 1974/75, based in Milan, Italy, was a unique organisation, involving musicians, sound and lighting engineers, music critics and teachers, and concert managers. It was started as a kind of artists’ union, a federation of folk, rock, political song, jazz, avant-garde groups, but in a few months it became a concert agency and a record company; it held music courses for amateurs and published music tutorials; it helped managing the first multipurpose art/social centre in Milan. L’Orchestra promoted studies along various disciplinary perspectives (sociology, music education, ideological criticism, semiotics) that in some respects embody and in others help explain the development of popular music studies and of the International Association for the Study of Popular Music (IASPM) in Italy.
