Roc Nation leader Jay-Z explained in an interview what his label is all about, and why an artist must be patient to find success.

"J. Cole is pretty close, he's coming out in September," Jay told Angie Martinez on August 1st. "He's got a great album. Jay Electronica is working on a great album as well. He's pretty close. Bridget Kelly just released -- her debut song, 'Thinking About Forever' -- For me, if you're gonna come sign to Roc Nation, just realize it's going to take a second."

"I'm into artists. I'm not really into putting a single out. It takes a minute to build artists. It's just true. You can't come off the street and make a classic. Rarely does that happen. Lauryn Hill was in the business for 700 years before she put out the Miseducation of Lauryn Hill. She had to go through some things. You have to go through some things."
