Horizons of Rock Developing Everywhere or H.O.R.D.E. Festival was a touring summer rock music festival originated by the musical group Blues Traveler in 1992. In addition to travelling headliners, the festival gave exposure to bands, charities, and organizations from the local area of the concert.
The H.O.R.D.E. Festival began in 1992 as a solution to the dilemma of five East Coast bands that sought to avoid the club circuit in the summertime when other larger bands were playing to sold out amphitheaters .
Inspired by the previous summer's success of Perry Farrell's Lollapalooza Festival (which had been organized by Bill Graham Presents, the driving force behind Blues Traveler's record and promotional deal), John Popper and Dave Frey called upon their compatriots Widespread Panic, The Samples, the Spin Doctors, the Aquarium Rescue Unit and Phish to join them in a nationwide, summer, amphitheater tour. After originally christening the traveling spectacle "Horizons of Rock Developing East Coast", the vision spread to "Everywhere", and so the name was created. It is rumored that John Popper came up with the idea of the H.O.R.D.E. tour at the Arrowhead Ranch, a Deadhead-managed dude ranch in Parksville, NY that Phish, Blues Traveler, Spin Doctors, Widespread Panic and Aquarium Rescue Unit among others all played at 1991.
The H.O.R.D.E. tour can be viewed as the beginnings of the second incarnation of jam band music, as well as the improvisation, community of fans, and diversity of music that became trademarks of the genre. The initial incarnation of jam music, led and epitomized by bands like the Grateful Dead and the Allman Brothers Band, sparked a love for improvisational rock and jazz that was fostered by both the musicians and fans associated with the second wave of 'jam' music. The H.O.R.D.E. tour, featuring such new jam icons as the Spin Doctors, Phish, Widespread Panic, the Aquarium Rescue Unit (and subsequent Col. Bruce Hampton projects), including the Dave Matthews Band, allowed for a new generation of experimental improvisational music to hit a national audience. The festival was able to bring together a group of musicians with a similar approach to live performance, and thus consolidate fans of the music; hence, a scene was created around the developing genre.
The following artists participated in the H.O.R.D.E. festival:
There have been many rumors over the years that the band will eventually revive the H.O.R.D.E. tour. Asked about this in 2006, Blues Traveler drummer Brendan Hill replied, "The future is always bright for us, and we are constantly thinking about the future, maybe two or three years in advance." After many years of rumors, the H.O.R.D.E. Festival is officially back on July 9th, 2015. It will feature the Blues Traveler, 311, The Verve Pipe and Big Head Todd and the Monsters. The festival will be at the DTE Energy Music Theatre in Clarkston, Michigan.
