This is a list of songs recorded by the American hardcore punk band Black Flag.
 This list does not include any alternate or live versions of songs.
 The song "Crass Commercialism" from the compilation album Everything Went Black, is not included, as it is a collection of radio advertisements for Black Flag shows, as well as the six spoken work songs from Family Man.
 The Minutemen collaboration EP Minuteflag is also not included.
 This list is ranked in rough chronological order, and includes the most prominent recordings of each song.
 For instance, the songs "Six Pack" and "Damaged I", which are most known for being released on Damaged, were previously released (as alternate versions) on their third EP and first single respectively.
 Similarly, several songs, specifically from their second to fourth albums, were performed live earlier and recorded in demo form prior to having been officially released.
African blues is a genre of popular music, primarily from West Africa.
 The term may also reference a putative journey undertaken by traditional African music from its homeland to the United States and back.
 Some scholars and ethnomusicologists have speculated that the origins of the blues can be traced to the musical traditions of Africa, as retained by African-Americans during and after slavery.
 Even though the blues is a key component of American popular music, its rural, African-American origins are largely undocumented, and its stylistic links with African instrumental traditions are somewhat tenuous.
 One musical influence that can be traced back to African sources is that of the plantation work songs with their call-and-response format, and more especially the relatively free-form field hollers of the later sharecroppers, which seem to have been directly responsible for the characteristic vocal style of the blues.
("Give Me That") "Old-Time Religion" (and similar spellings) is a traditional Gospel song dating from 1873, when it was included in a list of Jubilee songs—or earlier.
 It has become a standard in many Protestant hymnals, though it says nothing about Jesus or the gospel, and covered by many artists.
 Some scholars, such as Forrest Mason McCann, have asserted the possibility of an earlier stage of evolution of the song, in that "the tune may go back to English folk origins" (later dying out in the white repertoire but staying alive in the work songs of African Americans).
 In any event, it was by way of Charles Davis Tillman that the song had incalculable influence on the confluence of black spiritual and white gospel song traditions in forming the genre now known as southern gospel.
 Tillman was largely responsible for publishing the song into the repertoire of white audiences.
 It was first heard sung by African-Americans and written down by Tillman when he attended a camp meeting in Lexington, South Carolina in 1889.

The following is an incomplete list of blues festivals, which encapsulates music festivals focused on blues.
 This list may have some overlap with list of historic jazz festivals and list of historic rock festivals, both later genres dependent on elements of the blues.
 The blues is a genre and musical form that originated in African-American communities in the "Deep South" of the United States around the end of the 19th century.
 The genre is a fusion of traditional African music and European folk music, spirituals, work songs, field hollers, shouts and chants, and rhymed simple narrative ballads.
 Blues has since evolved from unaccompanied vocal music and oral traditions of slaves into a wide variety of styles and subgenres, such as country blues, Delta and Piedmont, Chicago, West Coast blues.
 World War II marked the transition from acoustic to electric blues and the progressive opening of blues music to a wider audience, especially white listeners.
 In the 1960s and 1970s, a hybrid form called blues rock evolved, which was featured prominently in the Summer of Love, for example, and became ubiquitous at rock festivals.
The field holler or field call is a mostly historical type of vocal music sung by African slaves to accompany their work, to communicate usefully or to vent feelings.
 It differs from the collective work song in that it was sung solo, though early observers noted that a holler, or ‘cry’, might be echoed by other workers.
 Though commonly associated with cotton cultivation, the field holler was also sung by levee workers, and field hands in rice and sugar plantations.
 Field hollers are also known as corn-field hollers, water calls, and whoops.
 An early description is from 1853 and the first recordings are from the 1930s.
 The holler is closely related to the call and response of work songs, and arhoolies, to Afro-American and ultimately influenced strands of African American music, such as the blues, rhythm and blues, and spirituals.
