Passage: Metzger was born to a Jewish family in Mainz on March 23, 1932, to a hardware store owner and a homemaker. Some of his relatives perished in the Holocaust. At the suggestion of his sisters, Metzger's father moved to the United States in 1937, followed by his wife and sons in January 1938. Henry Metzger attended the Bronx High School of Science, as did his brother, then earned a bachelor's degree from the University of Rochester in 1953, followed by a medical degree at the Columbia University College of Physicians and Surgeons in 1957. Metzger completed his residency at Columbia Presbyterian Hospital, and joined the Public Health Service in 1959, through which he began working at the National Institutes of Health. After two years of post-doctoral study with Seymour Jonathan Singer, funded partly by the Helen Hay Whitney Fellowship, Metzger returned to the National Institutes of Health, working primarily in the National Institute of Arthritis and Musculoskeletal and Skin Diseases.

Passage: While in London performing at The Rainbow Theatre, Dingwall's, and trendy Cabaret Futura, the Bongos recorded their early singles and their well-received debut EP Time and the River for UK-based Fetish Records. Cover designs for their Fetish releases were created by influential graphic artist Neville Brody, who was soon to become the designer of The Face magazine. The group's love of avant-garde performers brought them in touch with artists such as Throbbing Gristle and Clock DVA who performed with them live in London, and on their recordings. Their debut U.S. album, Drums Along the Hudson, compiled from the band's British singles, was released in 1982 to widely favorable reviews on both sides of the Atlantic. While Trouser Press suggested that the group "may trade a certain amount of substance for easy appeal," it added that "there's no better musical equivalent of whipped cream anywhere." Writing in the Village Voice, Robert Christgau dryly commented that "for all their jumpy originality [the songs are] still slight, and Richard Barone's lyrics are so oblique you have to wonder what his angle is." In 2007 however, Jim DeRegotis wrote in the Chicago Sun-Times: "The initial impression of naiveté is offset by deceptively simple lyrics that actually hint at deep, dark mysteries and unfathomed mystical enigmas." The group's cover of T. Rex's "Mambo Sun" reached No. 22 on the Billboard Dance Chart. A thriving Hoboken pop scene emerged, triggered by the Bongos and Maxwell's, which gained national media attention, and drew many bands and fans to the city. An August 1, 1982 article in the New York Times Real Estate section hinted at the scene's popularity as an influence on increasing rents and property values.
