WMOT/Roots Radio 89.5 FM will be the flagship live broadcaster for Saturday’s benefit concert to help those affected by the fatal Smoky Mountain wildfires that ravaged parts of the Gatlinburg, Tennessee, area in late November.

In addition, NPR Music-affiliated World Café and the VuHaus digital music video service will host the video stream of the show produced and served by Music City Roots, the Americana radio show produced live on stage at The Factory at Franklin. Roots emcee Jim Lauderdale is among the performers in “Mountain Tough.”

All this week, artists and radio stations have been signing on to support “Mountain Tough,” an all-day, free outdoor musical celebration and fundraiser that will be held from 10 a.m. to 9 p.m. Saturday, Dec. 17, at 705 Parkway in Gatlinburg.

The full show will be carried by flagship broadcaster WMOT/Roots Radio 89.5 FM (http://wmot.org), which serves Middle Tennessee from the College of Media and Entertainment at Middle Tennessee State University. The show is being produced by Yee-Haw Brewing Co., Ole Smoky Moonshine, Music City Roots and the Gatlinburg Convention and Visitors Bureau.

The word went out on social media Wednesday just after noon from Zac Brown Band: Gatlinburg, Tennessee, is open for business & welcoming visitors!
