A Christian music festival (also known as a Jesus music festival or simply a Jesus festival) is a music festival held by the Christian community, in support of performers of Christian music.  The festivals are characterized by more than just music; many feature motivational speakers and evangelists, and include seminars on Christian spiritual and missions topics, service, and evangelism.  They are often viewed as evangelical tools, and small festivals can draw 10 times the crowd of traditional revival meetings.  While the central theme of a Christian festival is Jesus Christ, the core appeal of a Christian music festival remains the artists and their music.  Critics point out that the dichotomy of business and religious interests can be problematic for Christian festivals.  In similar ways as the Christian music industry in general, festivals can be drawn away from their central theme and gravitate toward commercialization and mainstream acts in an attempt to draw crowds. Rich Mullins (October 21, 1955 – September 19, 1997) was an American contemporary Christian music singer and songwriter best known for his worship songs "Awesome God" and "Step by Step".

Joe Isaacs, formerly a singer and banjo player in the group, has left since his 1998 divorce from Lily Isaacs.  He now does solo work on a far more localized level. This incomplete list is specifically for Christian music performers in the gospel music genres who have either been very important to the genre, or have had a considerable amount of exposure, such as in the case of one that has been on a major label.  This list includes artists that perform in traditional gospel music genres such as Southern gospel, traditional black gospel, progressive Southern gospel, urban contemporary gospel, gospel blues, Christian country music, Celtic gospel and British black gospel as well as artists in the general market who have recorded music in these genres.  This list is not designed to include performers in the greater Christian music industry specifically contemporary Christian music performers and its subgenres.
