Jesus’ Blood Never Failed Me Yet is a piece of music composed by Gavin Bryars in 1971. It is based around a recorded loop of an un-named tramp improvising a hymn; eventually rich harmonies are played by a live ensemble of strings and brass, always increasing in density. The recording was originally made for a 1960s documentary by Alan Power which chronicled street life in London. Later when listening to the recordings, Bryars noticed that the clip was very in tune, and that it looped well into 13 bars. The tramp died before being able to hear the completed piece.
