There are two major artists known as Steve Lacy.

(1) Steve Lacy (July 23, 1934 – June 4, 2004), born Steven Norman Lackritz in New York City, was an American jazz saxophonist and composer recognized as one of the important players of soprano saxophone. Coming to prominence in the 1950s as a progressive dixieland musician, Lacy went on to a long and prolific career. He worked extensively in experimental jazz and to a lesser extent in free improvisation, but Lacy’s music was typically melodic and tightly-structured.
