The Pop Ups — the Brooklyn-based duo of Jason Rabinowitz and Jacob Stein — drew more than 120 families of preschoolers and a total of about 400 people to the Davis Academy on Sunday, Jan. 29, for a concert hosted by PJ Library with the help of the Atlanta Jewish Music Festival.

Nathan Brodsky, the PJ Library engagement associate for the Jewish Federation of Greater Atlanta, said more than 80 percent of the attendees participated in PJ Library before enjoying The Pop Ups’ mix of electro-pop children’s music and puppetry, and he said that percentage will rise now that more of the families have connected with PJ Library.
