Francis Grasso

Francis Grasso (March 25, 1949 - March 20, 2001)) was an American soul music disc jockey from New York City, best known for inventing the technique of beatmatching (sometimes referred to as mixing or blending) which is the foundation of the modern club DJ's technique.

Grasso, who attended Brooklyn Technical High School and Long Island University, started his DJ career in 1968 at a New York nightclub called Salvation II. When the primary DJ Terry Noel failed to show up on time one night, the owners offered Grasso a chance at the job. The crowd responded almost immediately and soon he had his first regular gig. It was there and at subsequent New York clubs such as Tarots and his most famous nightclub, Sanctuary — a former German Baptist church at 43rd Street & 9th Avenue (featured in the movie Klute) — where Grasso perfected his craft.

Grasso was the first DJ outside of the radio broadcasting business to require headphones as part of his setup. This allowed him to preview a record on one turntable while another played on the second turntable. By using headphones in combination with slip-cueing, he changed the art of DJing. The records that Grasso was mixing used live drummers and not beat machines. It took skill and a good ear to mix these records for more than a few seconds which Grasso perfected to longer and longer sequences.
