Done noodling, they start stomping. With that much emphasis on the riddim, you had to know they'd go native eventually. And, you know, the stylistic shift clarifies how cerebral the rest of the album is: despite the physicality of its sounds--the thumping bass, the pointed shards of guitar--it's a thinking man's album. It's intellectual in intent, being a self-conscious exploration for new sounds. But a four-word chant above pounding, monotonous drums doesn't suggest the subtlety and refinement of the life of the mind. Sure, it's a bit more complex than that: bass is there supporting the force and power of the drumming, and the guitar adds additional texture, providing a chaotic background for Lydon's chant. Ultimately, though, this is the most basic, natural human music, a tribal chant with a thumping beat behind it. What a striking pair of ending tracks: here we have primitivism, and Radio 4 is futurism--mechanical sounds swirling around in an inhuman world.
