Old Dominion will headline Nashville’s 19th annual two-day “Let Freedom Sing! Music City July 4th,” joining previously announced acts including reggae artist Gramps Morgan, singer-songwriter Cassadee Pope and country artist Levi Hummon.

The celebration will take place on stage at First and Broadway; the downtown riverfront will also include what the Nashville Convention & Visitors Corp. is calling “the biggest fireworks show in the city’s history” synchronized to a live performance from the Nashville Symphony at Ascend Amphitheater.  CMT will nationally broadcast “Let Freedom Sing!” from 8:30 p.m. to 10 p.m., including a portion of the concert and the entirety of the fireworks show. The fireworks also will be streamed on visitmusiccity.com/july4th.
