This is what we found on Wikipedia regarding the Gospo Collective:

Gospel music is a traditional genre of Christian music and a cornerstone of Christian media. The creation, performance, significance, and even the definition of gospel music varies according to culture and social context. Gospel music is composed and performed for many purposes, including aesthetic pleasure, religious or ceremonial purposes, and as an entertainment product for the marketplace. Gospel music is characterized by dominant vocals and strong use of harmony with Christian lyrics. Gospel music can be traced to the early 17th century.

Hymns and sacred songs were often performed in a call and response fashion, heavily influenced by ancestral African music. Most of the churches relied on hand–clapping and foot–stomping as rhythmic accompaniment. Most of the singing was done a cappella. The first published use of the term "gospel song" appeared in 1874.

The original gospel songs were written and composed by authors such as George F. Root, Philip Bliss, Charles H. Gabriel, William Howard Doane, and Fanny Crosby. Gospel music publishing houses emerged. The advent of radio in the 1920s greatly increased the audience for gospel music. Following World War II, gospel music moved into major auditoriums, and gospel music concerts became quite elaborate.

Black and Southern gospel music are largely responsible for gospel's continued presence in contemporary Christian music, with soul music by far the best–known popular music variant. The styles emerged from the African-American music and American folk music traditions and have evolved in various ways over the years, continuing to form the basis of Black church worship even today. It has also come to be used in churches of various other cultural traditions (especially within Pentecostalism) and, via the gospel choir phenomenon spearheaded by Thomas Dorsey, has become a form of musical devotion worldwide. Southern Afroamerican gospel groups used all–male, tenor–lead–baritone–bass quartets. Sensational Nightingales, the Soul Stirrers, Swan Silvertones and the Dixie Hummingbirds were famous gospel groups. Christian country music, sometimes referred to as country gospel music, is a subgenre of gospel music with a country flair. Famous Christian country music performers were Grandpa Jones, Webb Pierce, Porter Wagoner and the Oak Ridge Boys. British black gospel refers to Gospel music of the African diaspora produced in the United Kingdom.
