and Gibson in the studio. Porter later told an interviewer: "Everybody said, 'God, what a different sound! Porter also preferred the luminous echo of the studio's EMT 140 plate reverb rather than its echo chamber, keeping the plates chilled in the air conditioned room to brighten their sound. In 1960 and 1961, an addition was built to provide office space and rooms for tape mastering and a lacquer mastering lab. Nashville painter and singer/songwriter Gil Veda—introduced to the Grand Ole Opry crowd as "The Spanish Hank Williams" in 1962—was the first Hispanic singer to record at RCA's Studio B. In her 1994 memoir, My Life And Other Unfinished Business, Dolly Parton recounted how she was rushing to her first recording session at Studio B in October 1967 (shortly after having signed with RCA Victor) and, in her haste to make the session on time, drove her car through the side wall of the building. She noted that the spot where her car impacted the building is still visible. Production style Quonset Hut Studio, RCA Studio B, and later RCA Studio A, were essential locations to the development of the "Nashville Sound." Chet Atkins and the production team at RCA Studio B, notably Steve Sholes, Owen Bradley, Bob Ferguson, and Bill Porter produced studio recordings in the Nashville Sound style, a sophisticated style characterized by background vocals and strings. The Nashville Sound both revived the popularity of country music and helped establish Nashville's reputation as an international recording center, with these three studios at the center of what would become known as Music Row. Historic landmark In 1977, the studio was made available to the Country Music Hall of Fame for tours, and in 1992 it was donated to the Country Music Hall of Fame by the late Dan Maddox. Until 2001, it was operated as an attraction when the new home for the Hall of Fame was built in downtown Nashville. From 2001 to 2011 the studio was co-operated by the Country Music Hall of Fame and Belmont University's Mike Curb College of Entertainment and Music Business program, which utilized the studio to teach students basic techniques of analog recording. In 2012, the National Park Service listed RCA Studio B on the National Register of Historic Places. The same year, operation shifted solely to the Country Music Hall of Fame and Museum, which offers daily scheduled tours of the studio.
