Despite recording for less than two decades, Mildred Bailey made a lasting impression, cutting memorable jazz sides throughout the '30s. Native American on her mother's side, she could do fast or slow equally well: Compare the bluesy drawl of her low-slung signature, “Rockin' Chair,” to the way she brims with outsized personality on the swinging “Doin' the Uptown Lowdown.” One of her earliest cuts, 1932's “Georgia On My Mind,” confirms her impeccable control of her fluttering voice, while “Shoutin' In That Amen Corner” is a heated warning lodged in the rougher side of gospel. Whether playing it poignant or peppy, Bailey sang with pure heart.
