There are a couple of bright spots in Kensington, Md., but nothing as youthful as Foundation, a new gallery, music venue, and event space situated in the area’s Antique Row. On Saturday, Foundation will celebrate its opening with a party taking place across two stages, featuring games, food, and all the rest. Come for the novelty, but stay for Astra Via, a collaboration between D.C. music-scene veterans Olivia Mancini (Washington Social Club, Olivia Mancini and The Housemates), pictured, and Jarrett Nicolay (Virginia Coalition). For Astra Via, Nicolay dispenses with the Dave Matthews Band-esque banjo that drives his other music, while Mancini’s vocals slip into Sheryl Crow territory on the group’s uplifting single, “Be Where You Are.” Dave Matthews Band and Sheryl Crow? That’s right. It’s pop, and friendly stuff at that—and it works. The Young Rapids, The Sea Life, Miles Midnight, and others round out Foundation’s ticket.

“Rock the Block” takes place from noon to 8 p.m. at Foundation Gallery and Liveroom, 3762 Howard Ave., Kensington. Free. fndtnarts.com.
