Gavin Bryars - Jesus Blood never failed me yet (full, audio only, no visual)

Jesus’ Blood Never Failed Me Yet is a 1971 composition by Gavin Bryars. It is formed on a loop of an unknown homeless man singing a brief stanza. Rich harmonies, comprising string and brass, are gradually overlaid over the stanza. The piece was first recorded for use in a documentary which chronicles street life in and around Elephant and Castle and Waterloo, in London. When later listening to the recordings, Bryars noticed the clip was in tune with his piano and that it conveniently looped into 13 bars.[2]
