Students: Welcome to Ann Arbor and to the Ark, a world-class club with music for all ages and tastes! Tonight's show is FREE with student ID. Philadelphia's Hoots and Hellmouth are the duo of singer-songwriters Sean Hoots and Andrew Gray (he's Hellmouth), augmented by mandolinist Rob Berliner and other musicians as needed. They call their sound "new music for old souls," and it has elements of alt- country, classic folk, and jam-band freedom. A great performance at the 2006 Philadelphia Folk Festival put them on the map, and they've built a following pretty much just by taking their music on the road.. There's a long list of artists who've played the Ark before they became household names, and Hoots and Hellmouth just might be the next name on the list.
