This needs little explanation. See excerpt from the album site below:

“Hieroglyphics’ Opio & Chosen Few’s Unjust team up for “Mark It Zero” Lebowski Tribute Album. With the concept of the album coming from a trip taken by Opio and Unjust to a screening of the Big Lebowski at the historic Red Vic Theatre on fabled Haight Streeet in San Francisco on 4.20 of last year, both Unjust and Opio prepare to release The Big Lebowski Tribute Album “Mark It Zero”. It was there at the Red Vic Theatre that the two men, even though they were in a confined movie theatre, thought “Fuck it, man” and fired up a joint of medicial Cali Kush prompting scores of other patron’s to do the same in the theatre, thus becoming quite the far out scene. As Opio & Unjust (who are both big fans of the cult classic) got deeper into the film, they came with the idea of the tribute.”
