The Viscounts were an American pop group from New Jersey, formed in 1958. They had one hit single, with Earle Hagen's instrumental classic "Harlem Nocturne" in 1959, which peaked at #52 in the U.S. Billboard Hot 100 chart in early 1960; it was re-released in 1965 and hit #39 the second time around. The single and album of the same title were originally recorded for the Madison record label, then both were reissued in 1965 on the Amy label, the Lp having a slightly different track listing than the Madison release.
