On Sunday, April 28, 10:30 and 11:30 a.m., Morris Arboretum hosts a program of music and dance to raise awareness of an invasive pest that is a threat to trees. The Relâche Ensemble, dedicated to the creation and performance of new music in Philadelphia, in partnership with Almanac Dance Circus Theatre, present a multimedia program of music and dance celebrating the natural world and raising awareness about environmental issues impacting southeastern Pennsylvania.

This program of two, 25-minute performances is centered around The Spotted Lanternfly, a new piece by Philadelphia composer Erica Ball, and will also feature the audience participatory work Rock Piece by Pauline Oliveros. The performances will take place at the grassy area next to the Summer House below the Rose Garden, pictured below.
