The Sentimentalists, also known as the "Clark Sisters" (and also as the "Original" Clark Sisters; so-called to distinguish them from the current gospel music group of the same name), were an American close harmony singing group, consisting of sisters Mary Clark Branson, Peggy Clark Schwartz, Ann Clark Terry, and Jean Clark Frile. Hailing from Grand Forks, North Dakota, they were a mere 17 to 23 years of age when they signed with the Tommy Dorsey Band in 1944 to replace the popular Pied Pipers, after the Pipers had quit Dorsey's band to go out on their own.
Although they never achieved the fame and fortune of some of their contemporaries (like the The Andrews Sisters and The McGuire Sisters), the Clark Sisters' recordings are highly prized by jazz aficionados for their unique vocal stylings in which they often emulate instrumental sections.
