"On an individual album basis, that clean, glossy sheen can be too glaring but when it's distilled into this history, it's appealing because it's seen in the context of an artist who's constantly on the move, constantly finding ways to adapt to what's hot without ever losing sight of who he is. That's a story that can only be told on a box set and that's why Chicken Heads is so valuable: it shows all the ways Bobby Rush kept the blues alive".
