Think of damask silk, decades old. Smooth, luxurious and elegant, but ragged around the edges and faded to the point of fragility. Such is Chris Connor’s voice on I Walk With Music (HighNote). The shadow of those breathtaking Atlantic albums from the ’50s looms large over these 10 tracks, reminding us that this is a singer whose smoky allure was nonpareil. But a range that was limited even then has grown restrictively narrow, and it’s impossible to ignore the cracks. When the mood calls for wistful reflection, as on “Where Can I Go Without You?” “Quiet Nights” and “This Heart of Mine,” Connor is still the master, soft as dimming firelight and heartbreakingly poignant. Anything more upbeat-“Route 66,” the Gershwins’ “Shall We Dance” or the ill-chosen “On the Road Again”-proves rough going. Midway through “Serenade In Blue,” Connor wonders, “Is there still a spark?” Indeed there is, but the years have sharply dampened its intensity.
