Taped 333-feet below ground within the majestic Volcano Room deep inside Tennessee's Cumberland Caverns, this "musical adventure" series features both well-established and top emerging artists within the broad spectrum of Bluegrass, Jamgrass, Roots and Americana genres. Artists include Old Crow Medicine Show, Andrew Bird, Yonder Mountain String Band, Ben Sollee, The SteelDrivers, Johnnyswim, BeauSoleil, Leon Russell, North Mississippi Allstars, The Wood Brothers, Alison Brown Quartet, and the Infamous Stringdusters.
Aimed at pre-schoolers, this series follows the adventures of Bob and his machines: Scoop the leader/digger, Muck the digger/dumper, Dizzy the cement mixer, Lofty the crane and Roley the steamroller. Bob's business partner Wendy and Pilchard the cat all help out in the builder's yard. Other characters include Farmer Pickles, his tractor Travis and the naughty scarecrow Spud -- who is always up to mischief.
