The Griswolds

Australian band the Griswolds, yes, named after the family in the "National Lampoon" movies, is breaking through with "Beware the Dog." The Wind-Up single, which debuts on Alternative Songs at No. 36, blends fun.'s recent wall-of-sound harmonies and pure-pop stylings with guitar-work reminiscent of Paul Simon's "You Can Call Me Al." (Fun fact: the band was previously known as Weekend at Bernie's until it settled on its other '80s-inspired name.)
 
Meghan Trainor

Meghan Trainor makes her Billboard Hot 100 entrance at No. 84 with her catchy, doo-wop throwback single "All About That Bass." The song from the 20-year-old Massachusetts native (more specifically, the island of Nantucket) emphasizes positive body image, with its celebratory lyric, "It's pretty clear I ain't no size two / But I can shake it, shake it like I'm supposed to do!" Now a Nashville resident, Trainor co-wrote Rascal Flatts' "DJ Tonight," which appears on the band's latest album, "Rewind." She hopes to complete her debut Epic album by early fall.
 
Chase Bryant

Chase Bryant's debut single "Take It On Back" is bubbling under Country Airplay, as the 21-year-old singer/songwriter/guitarist works on his first album for Red Bow (an imprint of the Broken Bow Music Group). He's co-producing the set with Derek George (Randy Houser, Joe Nichols). Bryant's influences include his grandfather, who played piano for Roy Orbison and Waylon Jennings, and his uncles, who formed '90s hitmakers Ricochet.
