Hiero Day, one of the Bay Area’s most cherished hip-hop and R&B events, returns for its 11th year on Labor Day, and there’s plenty to celebrate.

This year’s block party will commemorate the 50th anniversary of hip-hop and the 30th anniversary of “93 ’til Infinity,” the debut album of Oakland alternative hip-hop group Souls of Mischief, with two stages hosting more than 30 live performances including San Francisco’s Cellski and Oakland pianist/rapperKev Choice.

A number of hip-hop-related events, such as a Souls of Mischief mural reveal, will bookend the festival.

If you’re unfamiliar with Northern California’s deep rooted hip-hop legacy, here’s everything you need to know about Hiero Day.

What is Hiero Day?

Hiero Day is an annual celebration of rap and hip-hop music in the Bay Area, founded in 2012 by the nine-member Oakland rap collective Hieroglyphics. Over the years, the one-day festival has grown into one of the biggest events to honor hip-hop in Northern California.

The outdoor concert serves as a platform for a plethora of local talent, both up and coming and those long established in the world of hip-hop.

Past Hiero Day performers include Bay Area nativeKeyshia Cole, singer, drummer and producer Anderson .Paak and ’90s rapper Kool G Rap.

Where does it take place?

Hiero Day was held at Jack London Square last year, but this holiday weekend the event moves to Frank Ogawa Plaza in front of City Hall, a decision reflective of its new association with the mayor’s office and the city of Oakland.

The festival also took place at Frank Ogawa Plaza in 2021, but on a smaller scale as the Bay Area was emerging from the pandemic.

Affiliated events leading up to Hiero Day 2023 are being hosted at various establishments throughout Oakland, including Crybaby dance club, the Moxy hotel and Hungry Ghost Studio.

The inaugural festival in 2012 was held in front of the New Parish in Oakland. Since then it’s been hosted at various locations in the East Bay city, including at American Steel Studios in 2017.

When do festivities kick off?

Hiero Day takes place from 11 a.m. to 7 p.m. Monday, Sept. 4. Every year there is a lineup of related events leading up to the main showcase.

From 2 to 6 p.m. Saturday, Sept. 2, Koo Labs, a nonprofit organization that supports Black youth, is set to host a fashion show called “Hiero on the Runway” at 1035 Seventh St.

The reveal of a Souls of Mischief mural — created by lead artists David Burke, Pancho Pescador and Joevic Yeban — is scheduled for 1-2 p.m. Sunday, Sept. 3, at Hungry Ghost Studio, 850 42nd Ave. That same day, a Hiero Day pre-party is set for 2 p.m. at Crybaby Oakland, 1928 Telegraph Ave., which costs $30. A free Hiero Eve party at the Moxy begins at 6 p.m.

The holiday weekend closes out with an official after-party at Crybaby at 9 p.m. Monday, complete with a Souls of Mischief performance and meet-and-greet.

Who will perform?
