Billy Eckstine's Imagination (1992)

"Billy Eckstine's smooth baritone and distinctive vibrato broke down barriers throughout the 1940s, first as leader of the original bop big band, then as the first romantic Black male in popular music. An influence looming large in the cultural development of soul and R&B singers from Sam Cooke to Prince, Eckstine was able to play it straight on his pop hits "Prisoner of Love," "My Foolish Heart" and "I Apologize.""
