Mothership Connection is the fourth album by American funk band Parliament, released on December 15, 1975 on Casablanca Records. This concept album is often rated among the best Parliament-Funkadelic releases, and was the first to feature horn players Maceo Parker and Fred Wesley, who had previously backed James Brown in the J.B.'s. Mothership Connection became Parliament's first album to be certified gold and later platinum. The Library of Congress added the album to the National Recording Registry in 2011, declaring "The album has had an enormous influence on jazz, rock and dance music."
