Lady A is in a "Summer State of Mind"

Marking the first look at a new way of releasing music for the group, it is the beginning of more tunes to come. The trio plan to spontaneously release new music over the coming months, creating and connecting with fans in real time.

"When we got together and wrote this song a few months ago, it almost started writing itself," Hillary Scott said. "We were all looking ahead to the warmer months and those easygoing moments that we enjoy most. When we had a chance to perform the song for the first time during CMA Fest, the fans really got in the spirit. It was the perfect way to kick off the summer."

"Summer State of Mind" was written by Dave Haywood, Sam Ellis, Laura Veltz and Scott. The video will be released on Friday. During this month's CMA Fest, the trio debuted the new single, which will be featured during the CMA Fest primetime special (Aug. 3 at 7 p.m. on ABC).

Lady A also is launching its upcoming Request Line Tour with back-to-back nights at Nashville's Ryman Auditorium, on Aug. 13. The shows are meant to foster audience participation as fans will be an interactive part of the show itself, using a special phone number (615-882-1975) to request Lady A songs. A portion of the ticket sales will go to LadyAID, the group's philanthropic fund which supports multiple initiatives around the world.
