In the ‘50s and ‘60s, it was common for elderly black bluesmen who’d been working in the rural shadows for years to finally find some mainstream recognition, but today? Not too often. In fact, Leo “Bud” Welch may just be the last of them, a chiseled, grizzled Mississippian whose authenticity, you can rest assured, is not in question. The deal Welch made with label chief and producer Bruce Watson, the story goes, was that he’d give him a blues album, but only after he cut a gospel one. So now, at 82, he delivers I Don’t Prefer No Blues, the follow-up to last year’s Sabougla Voices. It’s all grit and mud and sweat, the kind of traditional roadhouse gutbucket grime and grease you’d be lucky to find on some old scratchy slab of vinyl in a Natchez warehouse way back when. Seize the moment—Welch’s brand of blues is an endangered species.
