Al Green was hands-down the dominant soul singer of the Seventies, and his run of albums, especially in the first half of the decade, was so consistently strong that it’s hard to pick a favorite. I’m Still In Love With You has the back-to-back perfection of “Love and Happiness” and “I’m Glad You’re Mine.” Let’s Stay Together has, well, “Let’s Stay Together.” But top to bottom, Call Me is the one to beat, with the effortlessly sexy title song and the devastating “Here I Am (Come and Take Me).” Covers of songs by Hank Williams and Willie Nelson seal Green’s linking of Memphis and Nashville traditions. And the closing song, “Jesus is Waiting,” turned out to be the bridge to Green’s future in the pulpit.
