The 538th Roadhouse takes one set to venture into some new territory, but it’s all blues at its root. Jackson Mud, Papa Mali, Sonny Landreth, Clay Shelburn, and Jeff Jensen really step up in this edtion. Looking through the playlist for the hour, I have no doubt at all about two things: that the 538th Roadhouse is another hour of the finest blues, and that it’s another hour of the finest blues you’ve never heard.
