Today is the 18th anniversary of Biggie’s death.

With his surprise second album due out in two weeks, Kendrick Lamar is back on the radio circuit. This morning, he stopped by Los Angeles station 92.3 for an interview with host Big Boy and a freestyle session that saw him commemorate the death of the Notorious B.I.G. by rapping over a handful of his beats.
