Kendrick and Dre. Mashed. And it works well. Mash-ups are tricky, and full mash albums are even harder–because that much material is hard to mine. The only criticism here is that Lamar’s lyrics are so distinctive, it’s hard not to hear them in their original form–and that goes triple for many of the beats here, from huge Eminem songs and other monster hits. Still, it’s a fun way to get people who don’t know Kendrick’s stuff to give him a listen.
