On Adventures In Eville, Eleventyseven pursue their fusion of frothy sounds, wacky sci-fi imagery, and underlying Christian faith in typically relentless fashion. The South Carolina trio doesn’t slow down an iota on their third album as they continue to pitch their music squarely at teenaged believers. Singer Matthew Langston manages to sound cheeky, giddy and sincere all at once, making even his goofiest lyric scenarios seem like more than mere silliness. Case in point: “Evil Genius,” an eruption of power-pop exuberance spurred on by a galloping beat and gurgling synthesizers. Equally energizing are “Trying’” (an upbeat motivational anthem) and “Prom Night” (a high-gloss snapshot of Senior Year romance). The band reaches for a wider perspective on “Back When We Were Kids” and “End of Time,” though deep ruminations aren’t their strongest suit. “Nightmare” — a song about a girl or, possibly, God — adds some welcome guitar crunch to the trio’s frenetic attack.
