If you happened to be stuck in traffic in NYC around noon today (or following @okayplayer on twitter), the god of sample-flipping was smiling on you. That’s because our own afro-rocking overlord ?uestlove was invited to hold down Mr. Cee‘s Old School at Noon slot on the infamous radio station Hot97 as part of a series Cee calls “Black Fist Fridays”–and dedicated the entire hour to the productions of J Dilla, who would have celebrated his birthday on Tuesday and lost his struggle with the deadly disease lupus six years ago today. He also spoke to XXL Mag extensively about what made Dilla the greatest rap producer of all time (Questo’s words but, yes, I am printing it as if it were an indisputable fact) from the big picture to the specific moments that made some of our favorite records. Stream or download the mix–which contains all sorts of unreleased goodies teased throughout–below (via Miss Info), peep a choice quote and then read the full interview at XXL.
