To promote his newly-released album I Decided, Big Sean made his way by the Hot 97 studios on Thursday evening to chop it up with Funkmaster Flex. But rather than just discussing the album, Flex asked Sean to bless the listeners on air with a freestyle which he happily obliged to.

Going in over various beats like Freeway’s “What We Do,” Mobb Deep’s “Quiet Storm” and Nas’ “Oochie Wally” to name a few, watch the Detroit rapper go off-the-top for nearly 8-minutes straight in this dope freestyle (below).

If you haven’t already, be sure to give I Decided a listen here right on HNHH.
