Blue County attracted a diverse crowd of about 200 onlookers during a half-hour lunchtime concert Tuesday (Sept. 6) at Union Square Park in New York City. The duo’s set included “Good Little Girls,” “That’s Cool” and a medley of “Pink Houses” and “Slow Ride.” Erika Jo, Big & Rich, Gretchen Wilson, Cowboy Troy and Billy Currington are also participating in the outdoor music series, which concludes Thursday evening. Chevrolet is sponsoring the outdoor concert series to coincide with the announcement of this year’s CMA Award nominees during a Wednesday (Sept. 7) press conference in New York. CMT will air the nominations live at 10:15 a.m. ET during a special edition of CMT Insider.
