Page "A cappella" Paragraph 24

A cappella can also describe the practice of using just the vocal track ( s ) from a multitrack, instrumental recording to be remixed or put onto vinyl records for DJs.

Artists sometimes release the vocal tracks of their popular songs so that fans can remix them.

One such example is the a cappella release of Jay-Z's Black Album, which Danger Mouse mixed with The Beatles ' White Album to create The Grey Album.
