Golden Gate Park will again roar to life this October as Hardly Strictly Bluegrass expands its 2026 roster, adding Los Lobos, gospel icon Mavis Staples, and a dozen fresh voices to a lineup that already boasts My Morning Jacket, Gillian Welch & David Rawlings, and Old Crow Medicine Show.

The three‑day festival, scheduled for Friday, October 2 through Sunday, October 4, will occupy Speedway Meadow and surrounding stages. Organizers project attendance close to the 750,000‑person figure set in 2011, making it the largest music event in Northern California.

Los Lobos, the Los Angeles‑based group famed for their 1987 hit “La Bamba,” join a roster that now spans bluegrass, country‑rock, gospel, and world music. Mavis Staples, a gospel and rhythm‑and‑blues legend who has earned five solo Grammy Awards, is the most high‑profile new addition. Lukas Nelson, frontman of Little Big Band, brings a contemporary edge. Other newcomers include Langford, Hogan & Timms, Marty Stuart and His Fabulous Superlatives, Bandits on the Run, Tift Merritt, Meels, Moonalice, Anna Moss, ¿Qiensave?, and the duo William Tyler & Yasmin Williams.

The core lineup, announced earlier in the year, features AJ Lee & Blue Summit, Hiss Golden Messenger, Kathleen Edwards, El Khat, Tyler Ballgame, John Craigie with The Coffis Brothers, Aaron Lee Tasjan, Darrell Scott String Band with Rob Ickes, Dug, Mama’s Broke, A Tribute to Joe Ely with the Flatlanders and Friends, Alison Krauss & Union Station, Jerry Douglas, Kam Franklin, Ismay, Jesse Welles and Sierra Hull. With six stages, the program blends bluegrass, folk, country, rock and world music.

Hardly Strictly Bluegrass has been free and non‑commercial since 2001, a philosophy championed by San Francisco venture capitalist Warren Hellman, who subsidized the event and rejected corporate sponsorship to keep the focus on music and community. After Hellman’s death in 2011, his heirs and foundation continued to fund the festival.

Golden Gate Park, the venue for the festival, is the largest urban park in San Francisco and the third‑most visited urban park in the United States, drawing an estimated 24 million visitors annually. Speedway Meadow has hosted the festival’s stages for years, offering a natural backdrop for diverse lineups.

The festival’s website notes that additional artists may be added in the coming weeks, indicating that the 2026 bill will continue to evolve. Organizers emphasize that the free admission model allows a broad cross‑section of the Bay Area to experience a wide range of music.

Hardly Strictly Bluegrass’s expansion underscores its reputation for blending traditional bluegrass roots with contemporary and genre‑crossing acts. By adding performers such as Los Lobos and Mavis Staples, the festival broadens its appeal beyond bluegrass purists while still honoring its origins.

Festival organizers have not yet released a full schedule, but the 2026 program is expected to feature the new acts across the six stages over the three‑day weekend. Attendees can anticipate acoustic sets, full‑band performances and collaborative showcases.

Hardly Strictly Bluegrass remains a key cultural event for San Francisco, drawing crowds that rival the city’s population and providing a platform for both established and emerging artists. The 2026 expansion reflects the festival’s ongoing commitment to musical diversity and community engagement.

The festival’s official website and social‑media channels will provide updates on stage times and any further additions to the lineup as the event approaches.
