East Coast, stand up. One of Brooklyn’s grimiest up-and-coming spitters $ha Hef enlists two of the A$AP Mob’s finest for his new effort. “Mob Season” features bars from A$AP Twelvyy and production by A$AP P On The Boards. $ha Hef has released the song to promote his forthcoming album Street Treat B4 Super Villain, which will arrive on August 18. All of those rap-diehards who included only the most gully cuts from Mobb Deep and The Lox in their street-stomping playlists; this is for you.
