The Condon Shell hosts A Day in the Park with Ramble on Rose and Spoondrift. New to the local scene, Spoondrift is a jam band whose music exudes electric Americana with a psychedelic tinge. They’ll take the stage from 2 to 3:30 p.m. Ramble on Rose, which brings a fresh approach to the music of the Grateful Dead, will follow from 4 to 7 p.m.
