On January 25, 1995, Nas and Mobb Deep appeared on Tim Westwood's Radio 1 Rap Exchange up at Hot 97 with Funk Flex, as they kicked an impressive 10-minutes of trading (written) verses over the Infamous Mobb Deep's "Shook Ones Pt.2" instrumental. The homie DJ Step One shared the audio online and today felt like a good day to pass it along, too. We call these "FreeOfStyles," like Big Daddy Kane and KRS-One used to say back in the day. Enjoy this throwback below, and I'll see if we can dig up the full audio of Flex spinning that night with other special in-studio guests in 1995.
