Hardly Strictly Bluegrass veterans Chuck Prophet and Patty Griffin, as well as Birds of Chicago, Los Coast and Shakey Graves, have been announced as additional performers at “Let The Music Play On,” a live-streamed festival that will take place the first weekend of October in place of the gathering at Golden Gate Park.

They will join previously announced artists Emmylou Harris, Buddy Miller, Steve Earle & the Halfgrass Dukes, The War and Treaty, Amythyst Kiah, Alison Brown, YOLA, John Doe of X, Aaron Lee Tasjan and Sierra Ferrell.

Let the Music Play On is a celebration of the 20th anniversary of HSB and will include a combination of new performances with archival sets, interviews and more.

“As time marches on, what roots music is should change, ya know?” Shakey Graves’ Alejandro Rose-Garcia said in a written statement. “I think it’s just storytelling… a product of that time. I think that there’s something that is really pure to always go back to. I think that Hardly Strictly is doing it right in the sense that there will be a human experience within the music.”
