“I’m tired of talking about the past,” declares newly recruited lead singer Cody Collins on Lonestar’s Party Heard Around the World, and indeed the veteran country-pop band makes a deliberate effort here to retool themselves for another run at the charts. Replacing long-time frontman Richie McDonald, Collins injects some youthful vigor into the band’s bloodstream, moving them away from the family-friendly tone of “Mr. Mom” and “My Front Porch Looking In” towards a more freewheeling sound. Of course, Lonestar hasn’t abandoned the harmony-laden balladry that earned them so much success from the early ‘90s onwards. “You’re the Reason Why” and “Let Me Love You” are unabashedly romantic offerings, served up with more gusto than the band has shown in some time. Upbeat tracks like “Live, Laugh and Love” and “Goodbye Is Goodbye” move with sleek guitar-fueled drive, while Collins’ swaggering vocal on “Y.O.U.” sparks some real heat. The album’s title tune is a Saturday night anthem that definitely signals that Lonestar has loosened up.
