Jazz Owl Reviews: review by Bret Arenson. The lush baritone voice of Johnny Hartman enriched many big bands in the Forties and Fifties including Dizzy Gillespie's and Erol Garner's. But in the sixties he recorded many fine albums as leader and with all-star small groups. Although not as popular as some of his other releases, "The Voice That Is" is an exceptional showcase of his beautiful talent.
