The duo will also launch an overseas tour this fall after a few domestic shows.

A special Gold Album Party will be held at Grimey's New & Preloved Music in Nashville on Wednesday, Sept. 26 at 6 p.m. The event will also celebrate "Barton Hollow" as the best selling album of all time at the record store. The event is free and open to the public and will feature a meet and greet with the band, a live DJ set, limited edition posters and a chance to win an official gold album plaque.

This achievement comes the same week the duo (consisting of Joy Williams and John Paul White) was nominated for two CMA Awards - for Vocal Duo of the Year and Musical Event of the Year (for their collaboration with Taylor Swift on Safe & Sound from The Hunger Games soundtrack). The Civil Wars recently won Duo/Group of the Year at the 2012 Americana Music Association's Honors & Awards on Wednesday.

After taking a short summer hiatus following the birth of Williams' son, the duo will resume touring this fall, including appearances at San Francisco's Hardly Strictly Bluegrass Festival and the Austin City Limits Music Festival.
