A country music concert featuring the Swon Brothers and Josh Gracin is set for 7:30 p.m. August 30 on the Ocean City Music Pier. In 2013, the Swon Brothers became the ﬁrst duo to make it to a season ﬁnale of “The Voice” with the help of their coach, Blake Shelton. The Swon Brothers released their self-titled album and received a nomination for CMA Vocal Duo of the Year in 2014. They have toured with Carrie Underwood and are now busy preparing new music, including the newly released single “What Ever Happened” from their new EP. Josh Gracin fans fell in love with the Michigan native and former Marine upon his ascension onto the country charts in 2004 with “I Want To Live.” The hits came in short order for Gracin – the chart-topper “Nothin’ To Lose,” “Stay With Me (Brass Bed)” and “We Weren’t Crazy” all hit high on the Billboard charts. Tickets for the show ($25 to $30) go on sale Thursday (April 4).
