Very well spoted Tom. This is a curious discussion, because I never put my mind on the subject. In a way, there's the classic style of Maurice and his classical guitar riffs sending us back to the past. But now mix this with a kind of tribal drumming, a primitive and sacred drumming of the timbales (the bass reinforcing this sound).
On the other hand you have Lawrence's lyrics, track names, dark voice and mood with some rural content (I worship the sun, Sunlight bathed the golden glow, etc.), sends us back to Rural Romanticism (Byron)
Felt music doesn't reflect his own time and place (the 80's in Birmingham) and that's why is very difficult to catalogue. In my article on Felt (articles section) I mention coming back from hollidays in Algarve with my friends, crossing Tejo (Tagus) River in the sunset in a VW van and listening to Felt in silence.
