Throwback Thursday: A few years back I had the opportunity to host a K Michelle concert featuring Jon B. As K Michelle was performing, I couldn't help but want to know more about Jon B's past hit single, Are U Still Down featuring Tupac and how that collaboration came about. I, myself, had never met Tupac Shakur but I have always had a love for his music. While K Michelle was singing her heart on stage, I was curious to know more about this Jon B and Tupac encounter. "Are U Still Down" peaked at #2 on the Billboard R & B chart back in 1998. It has been said this was Tupac's final rap verse he recorded before his death.
