Alan Glover (aka "Juice") is a progressive jazz musician, whose work has been characterized variously as avant-garde, free-jazz, post-bop and spiritual. Born in the Bronx, NY, Glover's artistic life has been one of social activism and expression in a variety of art forms. His early work as a film-maker during the civil rights movement dealt with powerful themes of cultural and political consciousness through works such as Birth and Mississippi Goddamn (based on the Nina Simone song of the same title)
During the 1970s, Glover turned his attention to music, performing extensively with his ensemble "The Juice Quartet." In Manhattan's East Village he founded the Firehouse Theater, a community arts center and important early influence on the movement later known as loft jazz. His musical work retains the same dedication to social commentary, often embedding these themes directly into the structure of his compositions, performances and liner notes.
As an author, Glover has written a study of music harmony titled The Musiversal Visual Aid. His unique approach utilizes shapes and visual relationships to depict a variety of harmonic structures. Glover also invented The Musiversal Scale Rule, a circular slide rule for progressive improvisers. Neck Work, is Glover's first published collection of political and theological essays.
