The “Every Time I Hear That Song” singer will star in a special primetime episode of PBS’s Emmy-winning live music series Bluegrass Underground, now entering its 8th season. But the concert’s setting may very well steal the show. Brandi Carlile Says Dolly Parton One-Up’d Her on Her Own Signature Song: ‘She Just Completely Takes Me to School’ courtesy The Caverns The episode is the first filmed in The Caverns in Pelham, Tennessee, a unique venue inside an ancient cave located at the base of Monteagle Mountain and in one of the most cavernous regions on earth, according to its website. WATCH THIS: Turns Out Most Country Stars Don’t Remember Winning Their First CMA Award It took about 18 months to get the underground space ready to be a fully functioning concert venue for the series, its owner, Todd Mayo tells PEOPLE. But the result should be pretty spectacular as the Caverns are “an acoustically perfect setting,” according to a representative for the locale.
