The heavy-lidded rap ensemble Cypress Hill will be hosting an all-day concert this Sunday to celebrate the release of their new album, "Cypress Hill IV," which has actually already hit stores.

The event, aptly titled "The Smoke Out," will feature opening performances by the reunited rap group Pharcyde, the Long Beach Dub All Stars (the artists formerly known as Sublime), and up and comers Jurassic 5 and Dilated Peoples.

Cypress will then close the show with a special midnight set.

The show, set for the San Bernadino Event Center, is being produced by "Industry Insider," a magazine devoted to "club culture and urban lifestyle" that Cypress' B-Real has a hand in.

Cypress Hill plans to take their show on the road sometime next month.
