Eli Rosenblatt, shown here performing at the Port Angeles Library in October 2015, returns for a countywide celebration of Día! on Saturday, April 30.

He’ll be at the Sequim Library, 630 N. Sequim Ave., at 10:30 a.m., the Port Angeles Library at 1 p.m. and Forks Library at 4 p.m. that day, when the North Olympic Library System joins hundreds of libraries across the nation in celebrating the 20th anniversary of El día de los niños/El día de los libros.

Rosenblatt, a bilingual musician, and friends lead the celebration with music to move and groove to in English and Spanish.
