Along with the Mills Bros, the Ink Spots were the most popular black vocal group of the 1930's and 40's, though their careers spanned such duration, that groups are still performing under the Ink Spots name. Their trademark style, with a buttery tenor vibrato over spoken interludes by the bass vocalist, and elegant yet understated accompaniment, generated a spate of hits, including their first big chart appearance with "If I Didn't Care" in 1939. Having found their niche, a series of similarly-produced songs, including "The Gypsy," "Java Jive," "I Don't Want To Set The World On Fire" and "Prisoner of Love," capitalized on the record-buying public's attention. Though there were many subsequent personnel changes, the group sustained both artistic quality and popular success, and no music collection is complete without the Ink Spots.
