More artists have been added to this summer's H.O.R.D.E. festival.|

Gov't Mule and Robert Bradley's Blackwater Surprise have been selected to headline the festival's second stage. Gov't Mule, which features singer/guitarist Warren Haynes and bassist Allen Woody -- formerly of the Allman Brothers Band -- and drummer Matt Abts, will be on the first half of the tour. Robert Bradley will pick up the reins midway through and finish off the tour.

So far, acts that have been confirmed for the main stage include Ben Harper and Barenaked Ladies (who will each play hour-long sets), Alana Davis (who will open each show with a half-hour set) and Blues Traveler (who will close the festival each night with a 90-minute set.)

A source for the H.O.R.D.E. tour told JAMTV they are working on confirming at least one other act for the mainstage and numerous performers for the second stage. Stay tuned for more information soon. (Ari Bendersky)
