Quiet storm is a late-night radio format, featuring soulful slow jams, pioneered in the mid-1970s by then-station-intern Melvin Lindsey at WHUR-FM, in Washington, D.C. Smokey Robinson's like-titled hit single, "A Quiet Storm", released in 1975 as the title track to his third solo album, lent its name to the format and to the radio program that introduced it to the public. Encompassing a mix of African American music genres, quiet storm music is distinguished by understated, mellow dynamics and relaxed tempos and rhythms. It can be soothingly pensive, or express romantic sentiment. Quiet storm music is similar to soft rock and adult contemporary styles, but it is more closely and unmistakably rooted in R&B and soul music, often with jazz extensions.
Today, quiet storm is a broad term given to an array of mellow, slow-groove contemporary R&B, soul and smooth jazz offerings of the type featured on Melvin Lindsey's WHUR program, and on myriad other stations that followed his lead—most notably KBLX-FM in San Francisco, which in 1979 became the first radio station in the U.S. to present a 24-hour quiet storm format (which lasted 32 years, until the station was acquired in April 2011 by Entercom Broadcasting and converted to straight-ahead Urban AC format).
Melvin Lindsey, a student at Howard University, with his classmate Jack Shuler, was first a disc jockey for WHUR in 1976 as stand-ins for an employee who failed to report for work. The response from listeners was positive, and Lindsey stayed on. Founder of Radio One Cathy Hughes, WHUR station manager, heard of the show's positive reception and responded by giving Lindsey and Shuler their own show.
