It’s country music’s biggest night! Set your alarm because you don’t want to miss the foot-tapping fun when all your favorite crooners reunite to belt out a tune or two during the 2015 “CMA Music Festival: Country’s Night to Rock,” a four-day music event, which was previously filmed for TV in Nashville during June.

According to reports, CMA vocal group of the year, Little Big Town, will return for a third time to host the sizzling, three-hour ABC event, which is set to air on Tuesday, Aug. 4, at 8 p.m. EDT. But despite being veterans at hosting the celebratory festival (that first began in 2004), Little Big Town band member Kimberly Schlapman confessed to Billboard that she still gets nervous before interviewing her fellow artists.

Prior to talking to “Drunk on a Plane” singer Dierks Bentley, Schlapman dished that her “hands started to shake” while speaking to the talented country icon – “just like I did with Tim McGraw last year,” she quipped.

The singer added what an “incredible” experience it has been to be a part of the “CMA Music Festival: Country’s Night to Rock” – not to mention hosting the beloved festival for three, exciting years.

“It’s been a fun three years, and it’s changed some over time as far as the things we’ve been doing. We were a little nervous and shaky the first year, but we’re a little more comfortable now,” she spoke about the evolution of the country music celebration.

The festive TV event will feature some of country’s hottest artists including Bentley, Jason Aldean, Lee Brice, Luke Bryan, Kenny Chesney, Eric Church, Brett Eldredge, Florida Georgia Line, Randy Houser, Sam Hunt, Lady Antebellum, Little Big Town, Brad Paisley, Maddie & Tae, Kip Moore, Rascal Flatts, Thomas Rhett, Darius Rucker, Cole Swindell, Carrie Underwood, Keith Urban, Chris Young and Zac Brown Band. Viewers can also expect HGTV’s “Property Brothers” Drew and Jonathan Scott to make an appearance throughout the lengthy show.

The 2015 “CMA Music Festival: Country’s Night to Rock” will air Tuesday, Aug. 4, from 8 p.m. EDT to 11 p.m. EDT on ABC. But if you're not near a TV, no need to fret. Country lovers can still watch the event by tuning in to the live stream, offered to viewers by ABC for free, via ABC Watch Live or through the ABC Watch Live Mobile App, which can be downloaded through the Google Play Store or the Apple App Store.
