The Grateful Dead, celebrating their 60th anniversary, will return to San Francisco's Golden Gate Park this summer with three ticketed shows by Dead & Company on Aug. 1, 2, and 3. The proposal for the concerts will be reviewed by the Recreation and Parks Commission. The band, known for its ties to the city's psychedelic era, has a rich history in San Francisco. The concerts are expected to draw large crowds and generate significant economic activity for the local area.
