DJ Premier via Complex:

Guru wanted six artists on Gang Starr Foundation. He said, ‘I’m going to sign three, and you’re going to sign three.’ I never got my three. So I said, ‘Let’s start with your three.’ It was Big Shug, Group Home, and Jeru. Jeru was the most ready, so we started with him. I cooked it up, and I thought about putting some melodies to it, but Jeru’s so grimy and hardcore, the beat was perfect for him. He didn’t need any extra keyboards, or melodic sounds. It just sounded raw, and no one made a beat like that. And I ended up making two albums with [Jeru]: The Sun Rises in the East and Wrath of the Math. I stopped working with Jeru because of business issues. I keep business and friendship separate all the time. So I was like, ‘Let’s just chill, and we’ll keep it cool.’ And we’re still cool to this day.
