Update (3/24): Kendrick's "IV" Instagram post is gone—but the new song "The Heart Part 4" is here.
Original story (3/23): Kendrick Lamar may have just announced his fourth album is on the horizon. The rapper wiped his Instagram account clean save for a single post, which is a simple photo of the Roman numerals "IV." While there isn't a caption, the cryptic message could surely mean his new LP is imminent.
Lamar previously hinted that his next album may not be focused on rap. He told Rick Rubin in a GQ Style interview in October, "Yeah, I think I got the confidence for it. If I can master the idea and make the time to approach it the right way, I think I can push it out." But if he does plan to step away from rap, it wouldn't be a far stretch as Lamar has toyed with contemporary jazz sounds and vocal melodies on To Pimp a Butterfly.
