San Francisco son Larry June enlists some big-name talent for his latest single. “Mad Now” features Bay Area’s current flag-bearer Iamsu! and OG Maco, as well as production by Black Key Cartel. The song is set to be featured on both a forthcoming project from June and an LA Leakers-curated mixtape from Iamsu!, who just released an impressive EP of his own a week ago. Larry June has collaborated with Iamsu! and OG Maco previously on songs such as “Came Up” and “Top Shelf,” though this serves as the first time he’s brought both of them together for the same song. Just a few months ago, June released a project exclusively produced by TM88, but it looks like far bigger things are ahead for the rapper. You can check out “Mad Now” above.
