Legendary Philly turntablist, DJ Jazzy Jeff, just dropped a tribute to the late Michael Jackson ... a mixtape titled He's the King ... I'm the DJ.

The mixtape is collabo Jeff is doing with UNDRCRWN. It will feature a collection of "popular favorites and rare gems from the King of Pop," according to Jeff's blog (DJJazzyJeff.com/Blog), including some of his own exclusive remixes.

He's the King... will take listeners "on a musical journey by opening with slow grooves like 'Lady in My Life,' followed by a smooth transition into more uptempo favorites," Jeff continued.

The tape is 49 tracks in length, and available for free via UNDRCRWN.com.

Additionally, a limited edition t-shirt by UNDRCRWN will be made available, featuring artwork which references, "The Fresh Prince," the television show that Jeff and former partner in rhyme Will Smith starred in.
