Complex spoke with DJ Premier, asking him to recount the stories behind his "classic records." Included in this is The Notorious B.I.G.'s "Unbelievable" and "Kick in the Door." Interesting stuff to start the "Unbelievable" write-up:

“I almost didn’t make the record. Big called me at the last minute, and said, ’Get me a track,’ and I told him, ’I don’t have time to make one.’ I had other deadlines to meet at the time. He was on his way to blow up, and I loved him, and I wanted to help, but I really just didn’t have the time. I used to see Big in the area all the time. Just to hang. Mister Cee put me on to Big, and we would go down to the store where we used to buy 40s. We’ll see Big, and he’ll be like, ’Yo, what do I got to do to get put on?’ And I said, ’Well, you messing with Puff.’ And he’s like, ’Yeah, but he’s taking too long.’ And I would be like, ’Nah, stay with him. He’s going to help you get rich.’ He was just impatient like all artists, but it’s a process.
