Kendrick Lamar’s new album, To Pimp A Butterfly is out on March 23rd. The album's first two singles come from opposite ends of the spectrum, emotionally and musically—we have the sunny, self-love anthem "i" and the dark and seething "The Blacker The Berry"—prompting us all to wonder what exactly Kendrick has in store for us. Now he's shared a third track from Butterfly, a song Pharrell Williams called "unapologetically black and AMAZING." While we think all of the songs we've heard from Butterfly so far qualify as unapologetically black and amazing, Pharrell is not wrong. Surprisingly, "King Kunta"—named after Kunta Kinte, the 18th century slave whose story is the basis of Alex Hayley's Roots—is an ode to 70s funk, not unlike "Housequake" from Prince’sSign 'O' The Times. It's irrepressibly catchy, the most tuneful Kendrick Lamar song yet. Also, Thundercat's bass line is absolutely bonkers.
