Luther Wright And The Wrongs have recorded a whole cd devoted to "The Wall", titled "Rebuild The Wall". Basically is "The Wall" re-done in a bluegrass format. Is bizarre...but tastefully done, I believe--not like your regular run or the mill 'tribute' album, that turns out to be novelty [aka "Hayseed Dixie"]. Translating the Queen's English into a hillbilly vernacular gives the project a touch of humor, and the bluegrass style seems to put more emphasis on the quality of the lyrics. The instrumentation is interesting, using mainly traditional bluegrass instruments, and the vocals are quality as well. The sound effects are, well, 'backwoodsy', for lack of a better term. Definitely worth checking out!
