By way of example, Mostofsky tells a recent story. Leo Svirsky, a pianist who grew up in Baltimore and now lives in the Hague and works at a music conservatory, was at Mostofsky’s house over the holidays performing a last-minute show. (Svirsky had been doing a date in Washington, D.C., and when Mostofsky learned there was nothing scheduled for Baltimore, he booked a show in his living room.) In addition to more regular improv/experimental stuff, Svirsky played a series of songs based on the Occupy movement. “I went up to him right after and was like, ‘These [songs] are amazing, I’d love to put out a record. When are you going back [to the Hague]?’” Mostofsky recalls. Svirsky’s answer was two days. The day after, Mostofsky had his piano tuned and invited Adam Cooke, of Lord Baltimore Recording, over to do an album. Look for the record soon on Ehse. “That’s how spontaneous it happens sometimes,” Mostofsky says.
