Carrie Hassler & Hard Rain "CHHR2" (Rural Rhythm)

The Bluegrass Underground inside Tennessee’s Cumberland Caverns will host Mountain Heart and Carrie Hassler & Hard Rain for its next concert — set for 1 p.m. Saturday, Oct. 24.

The caverns are located in McMinnville in mid-Tennessee. Bluegrass Underground’s Volcano Room is the setting for the concert series, which draws airplay from country radio giant WSM, home of the Grand Ole Opry, in Nashville, Tenn.

Mountain Heart has gained a reputation for presenting cutting-edge excellence in acoustic music circles since the group’s creation in 1999. Mountain Heart, or members of the band, have either won or been nominated for multiple Grammys, ACM, CMA, and IBMA Awards. They have appeared on the Grand Ole Opry more than 100 times.

Carrie Hassler & Hard Rain’s performances and a chart-topping album have made them one of the most requested bands in acoustic music. The group jumped on the scene late in 2006 with the release of their self-titled album on Rural Rhythm Records produced by Jim VanCleve of the band Mountain Heart.

The CD was an immediate success debuting at 11 on Billboard Magazine’s Top Bluegrass Top Album Chart (retail sales) and spending nine months in 2007 on the Bluegrass Unlimited National Bluegrass Survey Top 15 Album Chart (airplay).

Just over a month after the initial album release, Hassler’s single “Seven Miles From Wichita” hit the top spot on Sirius Radio’s Bluegrass Top 40 and went on to spend 10 months on the Bluegrass Unlimited Magazine’s Top 30 Single Chart. While that single was still charting, another single, “Going on the Next Train,” hit the same chart and appeared until January 2008. Yet another track, the gospel bluegrass song “Least That I Can Do” spent the last year on Bluegrass Now Magazine’s Gospel Truths Chart.

Other upcoming shows at Bluegrass Underground include:

• Nov 14 — J.D. Crowe & Williams and Clark Expedition
• Dec 19 — Bobby Osborne & The Rocky Top X-Press & Jesse McReynolds & The Virginia Boys
