DJ Premier and KRS-One have made magic together. On the latest episode of "So Wassup," Preemo reveals that he especially enjoyed working on KRS-One's debut solo album, Return Of The Boom Bap.

"This is the first time that KRS One embarked as a solo artist," PREEM explained. "Even though he was still representing BDP, he would now just go as 'KRS-One.' Almost as if it was two separate projects." And he acknowledged that it was a time that he grew into himself.

"1992—that's around the time I really felt like I am now a producer," Premier says. "Prior to that, I was still just getting my chops down and making it a lot better to call myself that. I wasn't claiming 'producer' at that time."

DJ Premier reveals that 1992 was the year his confidence took a quantum leap. After he got a call from his former manager, who informed him that the Bronx legend was looking for him. "Who's not going to flip out and be like 'what?'" Premier said. "Such a blessing, such an honor."

He gave KRS credit for popularizing the term "boom bap" and mapping out his approach for the East Coast classic. Kid Capri, Showbiz & A.G. and Kenny Parker worked on the album. But Premier acknowledges that he did the bulk of the album.

Premier wanted to be a part of the record's mastering session, and he was eager to be there. The only problem was the actual session was in the morning and he was exhausted.

"I twas a 10 o'clock session in the morning. During those times, I was not a morning guy," he shares. "Most of us artists, are always going into the studio late. We might go in the studio at 11 o'clock, we might go in at midnight, we might go in at 2 in the morning, just to start a session. That was normal for us."

He was ready to put "Stop Frontin'" at the end of the album. But he decided to sleep at D&D Studios and then take the DAT tapes over to the mastering session. But at the last minute, KRS decided to record one more song. DJ Premier resisted, but KRS pushed, urging the producer to create a "sleepy beat." DJ Premier found the soundtrack from Blacula.

"I found the sound," Premier says. "It was sleepy to me--nice, cracking drums, though."
