Wow! Excellent! So Kendrick Lamar, a young rapper from Compton who Dr. Dre signed to Aftermath/Interscope Records last year, recently released an album called good kid, m.A.A.d. city that has had much of the hip-hop community arguing about whether it is the best rap album of the year or the best rap album of all-time. I mean, it is really good. I’ve been listening to it a lot and it puts me in the mind of A Tribe Called Quest’s first album and OutKast’s second album. But apparently it could have been even better. Kendrick was reported to have recorded music with Lady Gaga earlier this year, but due to an unfortunate, all-too-standard industry snafu, none of the material was included on the final version of the album. Well, last night, Lady Gaga released a video she made of the version of the second song on Kendrick’s album, “Bitch, Don’t Kill My Vibe,” upon which she does appear. And it is great. Hooray for Lady Gaga! Hooray for Kendrick Lamar!
