(WBIR) Nashville's Ryman Auditorium, mother church of country music, is about to undergo a $14 million expansion, the first in almost two decades.

The actual historic music venue won't be touched. Instead, the project will expand the newer part of the building and will include a new brick and glass structure.

The Ryman will also get a new cafe and renovated box office, bathrooms and concessions.

Some of the biggest names in country music were on hand for Thursday's announcement. Ricky Skaggs, country music and bluegrass singer, said there no auditorium like the Ryman.

"There's something about this building that no one cannot feel when they're here," said Skaggs told WSMV. "There's a spirit here, and it's a good thing. So, to me, this is so important spiritually, the Ryman, but musically, it's everything."

Skaggs, Marty Stuart, and Vince Gill were all on hand to talk about what the Ryman means to them. Crews are expected to complete the expansion by July 2015.
