Watch Nas & J-Dilla's Psychedelic Video for 'The Sickness'

After being held in legal purgatory for 15 years, J-Dilla's posthumous vocal LP, The Diary, was released earlier this month. The first single from Jay-Dee's long awaited album is "The Sickness," and it's a fierce banger that sees the rapper/producer trade some fiery bars with Nas before a psychedelic backdrop. Check out the video above, and pretend you're not peering down a kaleidoscope in the process.
