Shelton, who is also a judge on the hit TV series "The Voice," will play on the sand near Caesars Atlantic City on July 31.
The concert is presented by The Atlantic City Alliance and its "Do AC" promotional campaign, and will be produced by Live Nation.

Shelton will be in the area ahead of his scheduled show the next night at New York's Madison Square Garden.
The concert is the latest in a series of free, large-scale events to attract visitors to Atlantic City.
Last year, Jimmy Buffet drew 50,000 fans to a free concert on the beach.
