The triple-parked strollers outside Dizzy’s on 5th will tell you when a City Stomp gig is happening. Inside, giddy kids—toddlers to grade-schoolers—scarf down high-end mac and cheese and sliders, fidgeting as they wait for the music to start. Frontman Kevin MacCallum is a local star: Many little ones know him from City Stomp, the preschool music program that explores Caribbean, African, Latin American, Irish and Jewish music in classes and live performances around the Park Slope area. The moment he picks up his guitar, kids start rocking out all over the snazzy retro diner. By song two, the grown-ups are grooving too. Seatings begin at 5pm and 6:30pm. Ages 6 months to 8 years.
