Reggae and grass: what a pair. I’m talking about the kind that you sit on in Dolores Park, of course, but I’m sure you won’t have any trouble finding the other kind while you’re there.

Tomorrow, some of SF’s finest purveyors of vintage rocksteady, ska, and early reggae 45s from the SF Vintage Reggae Society will be spinning in the park, live soundsystem style. We’re talking early reggae, folks. So you’re not gonna be hearing no Bob Marley’s Legend. No diss to that, but it’s not what all reggae sounds like.

2pm til the cops come. More on facebook. And here’s a cut to tide you over:

The Dave Hillyard Rocksteady 7 played an afternoon show at Bender’s last year and they are making a stop there again this Sunday.

This all-star group features members from the two of the best traditional ska revival groups of the ’90s, the Slackers and Hepcat. They will be joined by living legend and percussionist Larry McDonald of the Skatalites, Bob Marley and the Wailers, Toots and the Maytals, and Lee Perry. Expect heavy instrumental reggae and rocksteady sounds with Dave’s signature jazzy chops.

Free rocksteady and BBQ! Does it get any better? The show starts at 1:30pm 3pm at Bender’s on 19th and S. Van Ness. Here’s the event page, and a snippet from the last show:

Update: Dave says the show actually starts at 3pm.
