To Pimp a Butterfly is the third studio album by American hip hop recording artist Kendrick Lamar. The album was released on March 16, 2015, by Top Dawg Entertainment, Aftermath Entertainment, and distributed by Interscope Records. The album, which features the songs 'The Blacker The Berry' and 'i', was originally due for release on March 23 but is available to stream and download now. 'To Pimp A Butterfly' is the follow-up to 2012's 'Good Kid, MAAD City'. Lamar's two most recent releases, 'i' and 'The Blacker The Berry', both feature on the album's 16-song tracklisting. The latter was produced by Boi-1da, and references the 2012 killing of African American teenager Trayvon Martin. 'i' won Grammy Awards for Best Rap Song and Best Rap Performance in February. Speaking in a recent interview about the album, Lamar said the music ranges from "the intensely personal to the swaggeringly aggressive".
