The fourth Roxy Music lp, released in 1974 brings another strong effort from this art-rock band. Rockers like, "All I want is you "and "Prairie Rose" are backed by great ballads like "A really good time" and "Out of the Blue". Roxy was reaching the hieght of their career and "Counrty Life" is an important album in theur career. Second release of the U.S. version was minus the girls, but thankfully, they returned the cd's release.
