The band just announced that Domefest 10 will be held May 16-18, 2019 at Marvin’s Mountaintop in Masontown, WV [more info: Facebook, Wikipedia (the venue’s website was not available at time of posting)].
No other details have been announced yet, but obviously the big news is that the festival will be moving from its previous location in Bedford, PA to this new venue in WV (the site hosted the All Good Fest from 2003-2011).
