The Wikipedia article of the day for November 4, 2016 is Agharta (album).
Agharta is a live double album by American jazz musician Miles Davis (pictured) and his septet. Titled after the legendary subterranean city, it was recorded at a concert in Japan's Osaka Festival Hall in February 1975. Saxophonist Sonny Fortune, bassist Michael Henderson, and guitarist Pete Cosey improvised against a dense backdrop of riffs, electronic effects, cross-beats, and funk grooves from the rhythm section. Davis had already alienated many in the jazz community while attracting younger rock audiences with his radical electric fusion music. This dark, angry, and somber performance was seen as a reflection of his emotional and spiritual state—he was in physical pain from health issues and a substance abuse problem, and had been touring constantly with his band since 1973. The album was released in Japan in August 1975 by CBS/Sony, and in North America in 1976 by Columbia Records. A highly divisive record, it further challenged Davis' jazz audience and critics. It was reevaluated positively after a generation of younger musicians was influenced by the group's abrasive music and Cosey's effects-laden free improvisations, and is seen as the culmination of Davis' electric period.
