Jesus' Blood Never Failed Me Yet is a 1971 composition by Gavin Bryars based on a loop of an unknown homeless man singing a brief improvised stanza.
In 1990 the Gavin Bryars ensemble recorded a 60-minute version in a restored water-tower in Bourges, France, for Les Disques du Crepuscule.
A 74-minute version was recorded in 1993 for the Point label with Tom Waits adding his voice in the later sections to that of the homeless man.
[9][10] In April 2019, a 12-hour overnight version was performed in London's Tate Modern art gallery, directed by Gavin Bryars.
Performers included two groups of homeless people (one vocal, one instrumental), together with the Academy of St Martin in the Fields, the Southbank Sinfonia, and Bryars' own ensemble.
