People are excited about Artisphere: Arlington County is excited about its potential contribution to the ongoing transformation of Rosslyn, and arts professionals are excited about “community building.” After much anticipation and outreach, the cultural center finally opens its doors this weekend, hosting a preview gala on Friday, a BYT and Pink Line Project party on Saturday, and all-day arts programming on Sunday and Monday. DCist was invited to tour the facilities yesterday for a peek at the space, last minute preparations and to chat about their plans moving forward.
