Cervantes’ Masterpiece and AEG Presents have unveiled the artist lineup for this year’s 420 Eve On The Rocks concert at Red Rocks Amphitheatre. This year’s celebration of the “high holiday” will kick off with a performance from Ice CubeCypress HillE-40, and Too $hort.

The one-night event taking place in Morrison, CO on April 19th will serve as a smoke-filled gala for those who celebrate the unofficial cannabis holiday. 420 Eve On The Rocks will, of course, precede a larger 420 On The Rocks celebration the following evening on April 20th. That lineup will feature headlining appearances by Pepper and Method Man & Redman, as well as sets from ProfCollie BuddzDENMThe Underachievers, and very special guest Keznamdi.

Notably absent from the artist lineup is Snoop Dogg. Not only has the hip-hop icon performed at Red Rocks on and around April 20th several times in the past, but he also recently formed a supergroup with Ice Cube, E-40, and Too $hort. Early last year, the quartet announced the formation of Mount Westmore. The collaborative effort saw the release of two singles, “Step Child” and “Big Subwoofer“, along with the promise of a yet-unreleased full-length album.

A pre-sale for 420 Eve On The Rocks is now running through tonight at 10 p.m. MT (code: GOODDAY). The general on-sale will begin this Friday, February 4th, at 10 a.m. MT. Head here for tickets and additional information.
