Dirtbag Dan, the bearded ex-battle-rapper responsible for stoner anthems like “Slab City” and “Concentrate,” has released a new video for his song “Caddy PH Immortal.”

This is the third video from his upcoming album, 3RTYS, which is set to drop August 30. The song is a memorial for Robert Diaz and Robert Paulson, known respectively as battle rappers PH (fka Pumpkinhead) and Cadalack Ron.

Dirtbag Dan spoke with HipHopDX about the personal significance making this video:

“Caddy and PH had a lot more in common than most would assume. They were both battle rappers, but they were also respected musicians who personified the places they came from. They inspired. They left a legacy. To me, they’re immortal now. That’s what I wanted to write about.”

The video includes clips Cadalack Ron and PH, as well as a large mural Ron, painted in memoriam in Los Angeles.
