The Viscounts were an American pop and rock band active in the late 1950s and early 1960s. Known for their instrumental style, they often mixed pop, rock, and jazz, creating a unique sound that set them apart from many of their contemporaries. The band's most notable members were Harry Haller, Bobby Spievak, and Larry Vecchio who, together, produced their most recognized work, a cover of "Harlem Nocturne". This particular piece was instrumental in their gaining national recognition and significantly influenced the instrumental rock genre during that era.
