The East End Trio, known for their performances of favorites from the ’60s, ’70s, ’80s, ’90s and 2000s, are set to perform at the Riverhead Free Library. Their style, grace and originality in music is often referred to as “acoustic comfort food.” This free outdoor summer concert is set to take place in the outdoor courtyard of the library. Attendees are encouraged to bring a lawn chair and enjoy the music. The concert is made possible through the generosity of the Friends of the Riverhead Free Library.
