Double bill of documentaries about multi-platinum selling R 'n' B stars R. Kelly and Usher. A singer-songwriter and producer, R.Kelly has worked with many artists, such as Michael Jackson, Celine Dion, Janet Jackson and Mary J. Blige. Among his successes, however, there have been sex scandals and court cases. A singer-songwriter, dancer and actor, Usher first took to music aged six when he joined his church choir and he was discovered just eight years later by L.A. Reid. Releasing his first album while he was still in school, Usher has only continued to grow as a performer and music artist.
