Charlie Rich had been heading toward full-blown country-pop on his previous Epic records, but Behind Closed Doors is where Billy Sherrill pulled out all of the stops and created a heavily orchestrated, pop-oriented album. It's to Rich's credit that he never sounds like he's drowning amid the grand production and layers of instruments -- in an odd way, he thrives. While Behind Closed Doors doesn't have the casual eclecticism that distinguished all of Rich's past recordings, it is an expertly crafted album -- it's easy to see why it made the Silver Fox a superstar. All of the material, from the hit singles ("Behind Closed Doors,""The Most Beautiful Girl,""I Take It On Home") to the album tracks, are classy songs, designed to appeal to a maturing country audience. Furthermore, the arrangements expertly walk the line between pop and schmaltz -- the sound of Behind Closed Doors is the sound of early-'70s countrypolitan and numerous artists used the record as a template for their own style. Rich made better, grittier records, but the combined collaborative effort of the vocalist and Sherrill resulted in a seamless, influential work -- even if it is one that earned the scorn of hardcore country purists. ~ Stephen Thomas Erlewine, All Music Guide
