XXL celebrates 50 years of hip-hop with this moment:

March 15, 2015: Compton rapper Kendrick Lamar dropped his third album, To Pimp a Butterfly, via Aftermath/Interscope Records and Top Dawg Entertainment, on this day in 2015.

Coming off the momentous acclaim of his major label debut album, good kid, m.A.A.d city, in 2012, everyone in hip-hop had an ear out for what K-Dot would come up with next. Hailed as one of the most nimble, imaginative storytellers in the rap game today, Kenny's second album had high expectations. Originally set to drop on March 23, Top Dawg Entertainment, Aftermath and Interscope moved up the release, surprising fans with a late-night drop one day after the 20th anniversary of Tupac Shakur's Me Against The World.

The album's lead singles, "Blacker The Berry," "King Kunta" and "Alright," asserted an unapologetically Black message in the wake of the increase in police brutality in America and the shooting deaths of young Black men like Michael Brown, Tamir Rice, Eric Garner and more. Cuts like "Momma," "How Much A Dollar Cost" and "Institutionalized" examined Kendrick's personal struggle with newfound fame and guilt for leaving the hood that raised him.

To Pimp a Butterfly was almost immediately hailed as a classic among fellow MCs and music fans for its inventive use of funk influences and Kendrick's outstanding lyricism. Production credits on TPAB include Dr. Dre, Anthony "Top Dawg" Tiffith, Terrace Martin, Flying Lotus and Pharrell Williams. Though it was sparse with features, George Clinton, Snoop Dogg and Rapsody came through with memorable verses when they did assist.

Kendrick spoke on TPAB's message when he sat down for his XXL Winter 2015 cover story.

"The past few years or so has been very politically charged and controversial. From Trayvon Martin, to Eric Garner to Michael Brown and issues of police brutality and racism and for so many other reasons," he said. "All of it has really struck a nerve with me because when you experience things like that personally and you know the type of hardships and pain that it brings first-hand, it builds a certain rage in you."

"It brings back memories of when I’m 16 and the police come kicking the door in," he continued. "They don’t care that I’m a little boy and they stumped me in my back two times and they dragged me out the house and have us all handcuffed. It brings back those memories. Memories of losing loved ones. It brings back some of the most painful memories and deepest thoughts of real life situations that I didn’t even want to address on good kid. Or wasn’t ready to. Rage is the perfect word for it."

As far as accolades, TPAB was nominated for 11 Grammy Awards, including Best Rap Album and Album of the Year. At the 2016 Grammy Awards, K-Dot won five of his 11 nominations including Best Rap Performance for "Alright" and Best Rap Album but lost Album of the Year to Taylor Swift's 1989.

Kendrick Lamar's To Pimp a Butterfly serves as a reminder of the power of hip-hop.
