Spiritland is a document of an era when rock musicians looked to black. America for inspiration and future direction, from the gritty urban scowl of blues, the penthouse soul of upwardly mobile detroit to the sanctified yelp of otis radding. there are many much more well - known artists that we all know, some by groups with whorm you may not be familiar,either. There is the raucous funky blues of Nick Gravenites" Kiling my love, Mighty baby"s psych-soul and honk"s breze-rock.
