Sally Oldfield's musical career started in 1968, when she founded the folk music duo The Sallyangie together with her brother Mike. The duo recorded their first and only album Children of the Sun in August 1968. The songs on it are mainly written by Oldfield, and the album contained some of her brother's early guitar work. In 1973 Sally contributed vocals on Mike Oldfield's classic "Tubular Bells".
Oldfield's debut solo album, "Water Bearer", was released in 1978. The track, "Mirrors", peaked at #19 in the UK Singles Chart, spanning 1978 and 1979, and remained in that chart for thirteen weeks. Since then, she has released twelve solo albums.
