Keith Urban and Vince Gill are at it again. The two country stars will be returning to Nashville's Bridgestone Arena on April 12 for the annual All for the Hall benefit concert -- and they're bringing Luke Bryan, Sam Hunt and many more with them.

The show, dubbed Mashville: The Music City in 2016, will be the sixth Nashville-based All for the Hall concert. As always, Urban and Gill are serving as the musical directors of the highly anticipated event, and they've lined up Bryan, Hunt, Peter Frampton, Florida Georgia Line, Emmylou Harris, Jason IsbellMaddie & Tae and Maren Morris to perform.

“Nashville has become a dynamic and diverse musical melting pot,” Urban says in a press release. “While it remains the home of country music, an unbelievably talented community of songwriters, producers, instrumentalists, singers, bands and solo artists are rapidly changing the entire musical landscape in Music City USA. Our sixth All for the Hall event -- Mashville: The Music City in 2016 -- will celebrate that!!!!"

In addition to the who's-who of country music, Urban and Gill will be joined onstage by a group of Middle Tennessee students, who will debut an original song specifically written for the evening through the Country Music Hall of Fame and Museum's award-winning flagship education program, Words & Music. All for the Hall benefits the Hall of Fame, and since the show's beginning in 2009, the event has raised more than $2.6 million.

"The abiding support of these two country music superstars who continue to act as champions for this museum allows us to further our mission," says museum CEO Kyle Young of Urban and Gill's profound support. "The proceeds of this fundraiser are especially important, as they help to ensure that the history of country music is preserved, shared and continues to grow and evolve for generations to come.”

In past years, All for the Hall has included many country stars, such as Jason Aldean, Eric Church, Miranda Lambert, Carrie Underwood, Taylor Swift, Willie Nelson, Merle Haggard and many more.

Reserved seating for All for the Hall 2016 begins at $35, and VIP packages are also available. Tickets are scheduled to go on sale on Jan. 29 at 11AM ET through Ticketmaster.com, the Bridgestone Arena Box Office or by phone at 1-800-745-3000.
