It was a gorgeous late-summer weekend in Golden Gate Park as the beloved Hardly Strictly Bluegrass festival rang in 25 years, with stars of bluegrass — and jazz, and rock, and country, and folk, and other genres — serenaded a grateful SF audience.

Below, a selection of photos from this year's festival, by photographer Cheryl L. Guerrero, including shots of Grammy Award winner Samara Joy, the great Patty Griffin, and the one-and-only, HSB mainstay Emmylou Harris.
