Gretchen Wilson officially kicked off the 2009 CMA Music Festival on Thursday morning (June 11) in downtown Nashville with a handful of new songs. Wilson told the audience she expects to release the album, I Got Your Country Right Here, in late summer.

In addition to the title track, she also performed "If I Could Do It All Over Again" and "Work Hard, Play Harder" from the new album, as well as "Here for the Party," "Homewrecker," "California Girls," "Politically Uncorrect," "All Jacked Up" and "Redneck Woman."

Heavy rain and lightning forced the delay of the planned 10 a.m. start time for the concert at Riverfront Park, but the schedule following Wilson's opening set included appearances by Phil Vassar, Chuck Wicks, the Randy Rogers Band, Ashton Shepherd, James Otto, the Bellamy Brothers, Heidi Newfield, Diamond Rio and Neal McCoy.

The first evening concert of the four-day festival takes place Thursday at LP Field with a lineup that includes Dierks Bentley, Brooks & Dunn, Julianne Hough, Reba McEntire, Brad Paisley, Darius Rucker and Rascal Flatts.
