In the mid-1980s the bands Phish, Edie Brickell & New Bohemians, Blues Traveler, Ozric Tentacles, Widespread Panic, Bela Fleck and the Flecktones, Spin Doctors, Col Bruce Hampton and Aquarium Rescue Unit, began touring with Jam band-style concerts.

Document 7: Greensky Bluegrass: Greensky Bluegrass is a five-piece American bluegrass/rock band founded in Kalamazoo, Michigan in 2000. 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.

Document 11: Oakhurst (band): is a bluegrass-rock band from Denver, CO. Founded by bassist Johnny James Qualley and Singer Adam Patrick Hill in 1999, Oakhurst became a full-time nationally touring act in 2004 and has produced 5 records. 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.
