“ ...unlike Aretha, [Al Green's] only rival vocally, Al never sold himself short in the studio. Where the albums follow the vagaries of genius, the hits exploit Al's personal production line, every one a perfect soul record and a perfect pop record in whatever order suits your petty little values. Brashly feminine and seductively woman-friendly, he breaks free in a register that darts and floats and soars into falsetto with startling frequency and beguiling ease. He's so gorgeous, so sexy, so physically attractive that only masochists want to live without him. ”
