This time last year, the organizers of Terrain were toying with the idea of expanding the event into something grander than a one-night-only art and music showcase. And now that plan is on the cusp of becoming a reality: Currently in its seventh year, Terrain has been uprooted and moved to a new location, which will, following tomorrow night’s festivities, begin its transformation into the organization’s permanent space. Terrain’s four main organizers – Luke Baumgarten, Ginger Ewing, Patrick Kendrick and Diego Sanchez – have been working tirelessly since getting the keys to their new home a few weeks ago. Long housed in the former Music City Building, 1011 W. First Ave., Terrain now will be headquartered at 304 W. Pacific Ave., next to the train tracks in a century-old building that was once known as the Washington Cracker Co. You may have noticed the painted mural on the highest point of the building – “Home of SnowFlake Saltines” – which currently reads, thanks to a carefully placed banner, “Home of Terrain.”
