9th Wonder: "The Formula was raw. We were trying to make records on this album. Not radio records but records. A record that I feel got away was ‘Here We Go.' That’s the one where I was like, ‘Yo, we have to do a video for this. This is a jam.'

"But the session for The Formula took longer than Chemistry. It took about two weeks? [Buckshot] came down here to record that album. The Solution took about five days. I picked all the samples, and made all those records. That's what I was paid to do. It's not really a special story attached to it.

"'Hold It Down’ was a record with my R&B artist, Tyler Woods, and Kweli is on there. I really like that record. We did the video in Brooklyn. And it was a play off the movie Crash. And that was one of the videos Rik Cordero directed. We had some big records on there. It really could have been bigger if the playing field was even."
