Stevie J. and Joseline Hernandez sat down for an interview with Hip-Hop Wired recently, and Stevie recalled his days working with Bad Boy records producing for Diddy and the Notorious B.I.G.  Stevie praised Biggie for his ability to show heightened levels of focus when recording his music, as he could be engaging in conversations with people, drinking, and just hanging out, while at the same time coming up with creative lyrics to spit in the booth.  He also noted that he never saw Biggie with a pen and paper actually writing down his rhymes. 

"He had his mind focused on his agenda, whatever the song was.  He never had a piece of paper writing it down. He just had his weed in the studio and his liquor flowing and the Branson in the air. He just created from just what he heard. He could have a million conversations going on while the beats was still rolling and then come up with a song. How do you do that when there's like 20 ni--as in the studio talking and you writing to a beat? That's very hard to do, to concentrate. So I never saw an artist with such focus. Supreme focus."
