Marion Chingawassa Days Committee announces country music band Diamond Rio will perform June 4 in Central Park as part of the annual festival.

The musical act made history in 1992 as the first group to have a debut single, “Meet in the Middle,” reach No. 1 on the charts. They have sold more than one million albums and have nine No. 1 and 22 top-10 singles. Diamond Rio is a six-time winner of the Country Music Awards and Academy of Country Music and has been nominated 15 consecutive years by the Country Music Association for vocal group of the year — more than any other band in country music history.

The group was inducted in the Grand Ole Opry in 1998, has been nominated for 14 Grammy Awards, and was the 2010 Dove Award winner for “country album of the year.”

The committee will make more announcements in the coming weeks as entertainment is lined up to “Rock the Park” on June 3, along with other acts and events June 4.

Chingawassa Days buttons will go on sale in May for Diamond Rio and other entertainment and events during the weekend.
