Crossover jazz is a genre of music that is rooted in jazz but aims for mainstream popularity. Crossover was popular in the early 1970s. Crossover jazz retains an emphasis on improvisation but attempts to make that improvisation commercially successful. A frequently cited example of crossover is the music of Eumir Deodato.
In the wake of jazz fusion's decline from popularity among jazz and rock fans in the mid-1970s, jazz artists who continued to seek wider audiences began incorporating a variety of popular sounds into their music, forming a group of accessible styles that became known as crossover jazz.
Deodato got crossover hit single and album "Prelude" in 1972. And Bob James released crossover song "Night on Bald Mountain". Influential saxophonistGrover Washington, Jr. incorporated elements of pop music and Caribbean music into a sound based in hard bop, while singer Al Jarreau blurred the lines between jazz, pop, and soul. Other artists, such as The Rippingtons and Spyro Gyra, injected their pop-flavored instrumentals with Latin rhythms and electronic keyboards. Jamaican jazz band Jazz Jamica released reggae jazz album in 1994. They fused roots reggae rhythm with jazz harmonies and extended improvisation.
