Kendrick Lamar celebrated the coming release of his major label debut by inviting hip hop titans Dr. Dre, T.I. and the Game onstage with him during a concert on Wednesday night. Lamar, who has been praised by critics while attracting a massive fan base after his 2011 “Section.80” album last year, was promoting his album “good kid, m.A.A.d. city” with a concert at Club Nokia in Los Angeles, an event that still had social media buzzing almost 24 hours later.

The crowd went into a frenzy when Dr. Dre walked through a door onto the stage. Dre joined Lamar for “Compton” before the two also tore through “The Recipe,” which will appear on the deluxe edition of Lamar’s upcoming album.

Earlier this year the young rapper debunked rumors around his album’s title and release date by tweeting, “Let me personally announce the album date and CORRECT title. Then it is official. The record is called ‘good kid, m.A.A.d. city,” according to Pitchfork. “All lowercase. Except two letters in the acronym,” he added later.

The new album – which will be Lamar’s first release on Interscope/Aftermath – may not officially come out until next Wednesday, but the release is already earning reviews that won’t have fans disappointed.   

A review from hip-hop tastemaker Under The Gun complimented Lamar on his newfound sense of maturity while refusing to let go of the delivery that attracted so many fans to him in the first place.

“Just as previous material have given us glances at a life laced with inner-city struggle, drugs, guns, love, loss and family deeply rooted in their faith, the tracks on Lamar’s latest play like musical chapters in the latest book of an ongoing series about the life of a twenty-something on his way up,” the review wrote.

“Even when Lamar touches on darker subject matter and the struggles he and those he loves continue to struggle with, there is an overwhelming sense of determination to overcome everything that reverberates throughout each track. Lamar recognizes he has a long way to go, and he uses this album to share that journey with the listener while still taking time to celebrate good.”

One of the reported highlights of the “good kid, m.A.A.d. city” is Lamar’s collaboration with Drake. “Poetic Justice,” which you can stream below, sounds like an obvious choice as the album’s first single. MTV reports that although Lamar’s new album has already leaked he probably has little concern about failing to repeat the success of “Section.80.”
