Martina McBride opened the show and Rascal Flatts closed it Tuesday night (Feb. 21) at 3rd & Lindsley, a club near downtown Nashville. The private party, presented by Big Machine Label Group and CMT Radio, was one of the after-hours events kicking off this year's Country Radio Seminar, an event attracting radio programmers and on-air personalities from throughout the nation. In addition to McBride and Rascal Flatts, the performance featured other top acts from Big Machine Records, the Valory Music Co. and Republic Nashville, including chart-topping acts such as The Band Perry, Justin Moore and Brantley Gilbert. McBride began the music with one of her signature hits, "Independence Day," and followed with "Whatcha Gonna Do" and her latest hit, "I'm Gonna Love You Through It." The Band Perry delivered their breakthrough hit, "If I Die Young," and "You Lie" while Moore opted for "Til My Last Day" (his upcoming single) and "I Could Kick Your Ass" (a rowdy track from his debut album). Gilbert performed "Country Must Be Country Wide" and his current single, "You Don't Know Her Like I Do." The party also allowed the Big Machine Label Group to present one of its newer acts, Edens Edge, and three even newer signings -- Greg Bates, Ella Mae Bowen and Thomas Rhett. Rascal Flatts closed the evening with a five-song set of "Why Wait," "Fast Cars and Freedom," "I Will Stand by You," "Life Is a Highway" and their latest single, "Banjo." Also in attendance were Sunny Sweeney and members of the Eli Young Band. The party was hosted by Big Machine Label Group president and CEO Scott Borchetta and CMT Radio Live's Cody Alan. Afterwards, many in attendance headed to the nearby Mercy Lounge, where the Mavericks were scheduled to play a reunion gig. The band, which recently signed to the Valory Music imprint, will be touring later this year with three of its founding members -- lead vocalist Raul Malo, bassist Robert Reynolds and drummer Paul Deakin.
