De Lucía was noted for his fast and fluent picados (fingerstyle runs). A master of contrast, he often juxtaposed picados and rasgueados (flamenco strumming) with more sensitive playing and was known for adding abstract chords and scale tones to his compositions with jazz influences. These innovations saw him play a key role in the development of traditional flamenco and the evolution of new flamenco and Latin jazz fusion from the 1970s. He received acclaim for his recordings with flamenco singer Camarón de la Isla in the 1970s, recording ten albums which are considered some of the most important and influential in flamenco history.
