Good jazz ballads don’t just conjure the comforting bittersweetness of love, but the world in which such a feeling has the space to exist: quiet, starlit, black-and-white; rainy, maybe, or at least with a chance of it. The classics here channel it perfectly, and the modern material captures a mood equally displaced in time. Lovelorn, lovesick, love-saturated or just feeling dreamy.
