Wynonna will celebrate her 25th year in country music with a summer road trip behind "Sing: Chapter 1," her first studio effort in six years.

The North American outing gets underway Saturday (6/13) with a headlining performance at Nashville's CMA Music Festival. Naomi Judd, Wynonna's mother and the second half of the award-winning duo The Judds [ tickets ], will make a guest appearance. The 13-date itinerary, which includes one other billing as The Judds July 2 in Uncasville, CT, wraps with a three-night stand Sept. 25-27 in Las Vegas. Details are shown below.

Wynonna, who will celebrate the Fourth of July with a free concert alongside the Nashville Symphony at Riverfront Park, is supporting her seventh solo album, "Sing: Chapter 1," which surfaced in February and peaked at No. 5 on Billboard's Top Country Albums chart.

"This record, it sort of needed to be my joy and sorrow record," Wynonna explained in a message posted at her website. "I get so much feedback from the world that I have a hard time sometimes maintaining my spiritual integrity. I think this record was just my answer to a real need to cry out and say, 'This is who I am ultimately.' The songs are not just, 'I think I'll do a campy record with standards."

The mostly-covers album features songs from Burt Bacharach ("Anyone Who Had a Heart"), Hank Williams ("I'm So Lonesome I Could Cry"), Merle Haggard ("Are the Good Times Really Over") and Stevie Ray Vaughan ("The House Is Rockin'), as well as one original song, "Sing," which was written by fellow country singer Rodney Crowell.
