He co-curated the 2011 MOCA show Art in The Streets with Jeffrey Deitch and Aaron Rose, featuring world-famous artists RISK, Barry McGee, Banksy, Os Gemeos, Shepard Fairey, and Mister Cartoon, among others, while setting all-time attendance records. In 2013, Gastman produced The Legend of Cool "Disco" Dan documentary film, narrated by Henry Rollins. It premiered at the AFI Theater in Silver Spring, MD accompanied by the book Pump Me Up: DC Subculture of the 1980s along with an exhibit of the same name at the Corcoran Gallery of Art. He produced and directed Wall Writers: Graffiti in Its Innocence, a documentary film about 60s and 70s-era graffiti, narrated by John Waters.
