Anyone who has followed Devin the Dude’s career knows that the man has an obsession with marijuana. While the Houston emcee is no longer signed to his long-time label home at Rap-A-Lot (he is now signed to independent label Razor & Tie), his departure certainly hasn’t changed his topical agenda. On a new collaboration with fellow kush-aficionado, Smoke DZA, Devin takes a drive on the herbal Highway. Responsible for both the middle verse and hook, the slept-on rap veteran transforms a riding-and-smoking track into a psychedelic masterpiece that should get great miles per gallon. It is unknown if the record, which is produced by Yung Boss Production team member Rob Holiday, will be included on the October 7 release of Devin’s new album, Landing Gear. Either way, Devin’s new album should light it up (pun intended).
