American country trio Lady Antebellum’s album, “747,” layers lovely harmonies with diverse and fascinating guitar riffs.

The 11-song record, which is being released today, is named after the group’s campaign to fulfill seven wishes for seven fans for seven days this week.

“Long Stretch of Love” kicks off the album with a contagious and simple guitar part with an acoustic chord progression. The song opens with heart-pounding quarter notes on the bass drum. The track features trade-off verses from lead singers Charles Kelley and Hillary Scott and impressive harmonies of the talented trio in the chorus.

“Bartender,” the album’s popular single, tells a story about drinking away pain. This catchy and fun song, which was released in May, kept me interested in “747” throughout the summer. The low guitar riff and creeping eighth notes on the banjo create a nice contrast to the powerful, in-your-face chorus.

“Freestyle” has an interesting vibe one wouldn’t expect from the trio. The track has a blues guitar riff while other instruments play in unison sporadically. The fast lyrics and vivid imagery depict a summer day of blasting music from Fleetwood Mac and Macklemore while the sun shines down and you have a good time with close friends.

“Freestyle” expresses the fun one can have by traveling the world, grabbing a drink and going on a spontaneous adventure.

As the song suggests, the trio is just trying to make the most of their summer.

Although summer has come to an end, the powerful harmonies combined with playful riffs on “747” can brighten your mood on a cool fall day.
