A year has passed since Sulu DC launched its performance series in the basement of St. Stephen’s Church in Columbia Heights. Inspired by the New York Sulu series — named for the well-known character from Star Trek — and recognizing the need for a similar community for Asian America/Pacific Islander (AAPI) artists in the greater Washington, D.C. area, a group of local organizers launched a similar group here in the District. And after mounting a year’s worth of successful events at venues ranging from the Ethiopian restaurant Almaz to U Street Music Hall, Sulu DC will celebrate its first anniversary with a special show on Saturday at its new digs, Arlington’s Artisphere.
