L$D is the name of a new and unexpected supergroup featuring Grimes, Kreayshawn, Blood Diamonds, and Tragik, and "Dont Smoke My Blunt B*tch" is their first release. From the description on YouTube, the song, which is built around the phrase, "I be that grimy mothaf*cka," and was produced by Grimes, was recorded in ten minutes. And the trippy video for it, directed by Tragik, was filmed in under an hour. Watch above.
