A music director may be the director of an orchestra, the director of music for a film, the director of music at a radio station, the head of the music department in a school, the co-ordinator of the musical ensembles in a university or college (but not usually the head of the academic music department), the head bandmaster of a military band, the head organist and choirmaster of a church, or an Organist and Master of the Choristers (a title given to a Director of Music at a Cathedral, particularly in England).

The title of "music director" or "musical director" is used by many symphony orchestras to designate the primary conductor and artistic leader of the orchestra. The term "music director" is most common for orchestras in the United States. With European orchestras, the titles of "principal conductor" or "chief conductor" are more common, which designate the conductor who directs the majority of a given orchestra's concerts in a season. In musical theatre and opera, the music director is in charge of the overall musical performance, including ensuring that the cast knows the music thoroughly, supervising the musical interpretation of the performers and pit orchestra, and conducting the orchestra.

Michael Joseph Jackson (August 29, 1958 – June 25, 2009) was an American recording artist, entertainer, and businessman. Often referred to as the King of Pop, or by his initials MJ, Jackson is recognized as the most successful entertainer of all time by Guinness World Records. His contribution to music, dance, and fashion, along with a much-publicized personal life, made him a global figure in popular culture for over four decades. The seventh child of the Jackson family, he debuted on the professional music scene along with his brothers as a member of The Jackson 5 in 1964, and began his solo career in 1971.

In the early 1980s, Jackson became a dominant figure in popular music. The music videos for his songs, including those of "Beat It", "Billie Jean", and "Thriller", were credited with transforming the medium into an art form and a promotional tool, and the popularity of these videos helped to bring the relatively new television channel MTV to fame. Videos such as "Black or White" and "Scream" made him a staple on MTV in the 1990s. Through stage performances and music videos, Jackson popularized a number of complicated dance techniques, such as the robot and the moonwalk, to which he gave the name. His distinctive musical sound and vocal style influenced numerous hip hop, post-disco, contemporary R&B, pop and rock artists.
