Most recently Barrel (2012) which was produced in Nashville, TN by Joe Pisapia. Whether it's in front of thousands of festivarians, hundreds of friendly bar dancers, dozens of fellow pickers, or each other in the studio, Oakhurst leaves it all on the field. This quintet brings their stories to the stage in the form of pure energy and passion for acoustic music. With gifted percussion and a driving low end, the banjo, guitar, fiddle and vocals have all the space they need to tell you a story. Love, life, loss, and whiskey are likely to be the topic of the day- come on and jump in the get down for a spell... The band spikes traditional bluegrass with rock & roll and a kamikaze rhythmic sensibility. That danceable concoction along with stringed shootouts, ringing harmonies, and citybilly swagger keeps the band in high demand. Oakhurst’s unpretentious, go-for-it interpretation of a genre that's roots are often handled reverently, sparks interest in bluegrass by folks who don’t know Doc Watson from Doc Holliday.

The band has evolved over the years, growing from 3 to 5 members, adding electric effects and touring with a full light show. "The whole notion of “traditional bluegrass” strangely remains a sticking point for plenty of the genre's faithful. Partly because of their name, every article written about the band addresses the fact that what Greensky does is “not quite” bluegrass. These depths have been plumbed. In fact, in their own promotional material, GSBG describes their sound as “their own version of bluegrass music, mixing the acoustic stomp of a stringband with the rule-breaking spirit of rock & roll.” Greensky Bluegrass is known for their improvisation, multiple set shows, and open audience recording policy (akin to Phish and The Grateful Dead) and have broken through to a multi genre fanbase covering songs from Bruce Springsteen, Aerosmith, John Hartford, Dawes, Phish, The Grateful Dead, Rolling Stones, Prince and more.

The band started presenting their energetic take on fiddle band music 4 times a day, 7 days a week at the Great Smoky Mountains Railway shortly after forming back in 1992. This afforded the group plenty of paid rehearsal time to hone a sound that has proven entertaining and distinctively theirs. Their repertoire includes music that was first recorded in the late 1920s and early 1930s, and spans geographically from Mississippi to West Virginia. The Freight Hoppers play hard driving old time music with an emotional, raw excitement that keeps one foot planted in the past and the other in the present. Of course that’s only when they keep their feet still, for this is high energy dance music of an older day played like there's no tomorrow. Finding their passion from a love of stringband music of the 1920s and 1930s, The Freight Hoppers have been entertaining crowds of fans at festivals and music halls alike as they travel around the country, and beyond. The heart of the band is held together by the fiddle and banjo combo of Merritt Smith and Frank Lee, while the rhythm section of Allie Burbrink on guitar and Andrea Smith on string bass hold down the ensemble. Based out of the Smoky Mountains of North Carolina, The Freight Hoppers draw from a deep source of rural southern music for their inspiration, and are proud to present music that is still very much alive and meaningful to today's world.
