Quick Answer: RCA Studio B was a music recording studio in Nashville, Tennessee, established in 1957 by Steve Sholes and Chet Atkins for RCA Victor. Originally known simply as the RCA Victor Studio, in 1965 the studio was designated as Studio B after RCA Victor built the newer, larger Studio A in an adjacent building. Located centrally in what would become Nashville's Music Row, the RCA Victor Studios were an essential factor to the development of the musical production style and sound engineering technique known as the Nashville Sound. In the two decades the studio was in operation, RCA Studio B produced 60 percent of the Billboard magazine's Country chart hits. The studio closed in 1977. Since 1992 the studio has been under the ownership of the Country Music Hall of Fame, which offers scheduled tours of the facilities.
