Although A$AP Rocky's highly anticipated debut album, Long.Live.A$AP, leaked more than a month early, the rapper isn't letting that get him down, as he releases singles as scheduled. You can also expect to see him doing a bunch of interviews as promo for the LP, most recently, one with NBC's The Grio.

While talking to NBC, A$AP Rocky speaks on one of the hugest records off the album- "1Train," which enlists massive features from Kendrick Lamar, Joey Bada$$, Action Bronson, Danny Brown, Yelawolf & Big K.R.I.T.

Rocky explains how he was channeling a '90s feel with the posse cut, "I really wanted to take back to the essence of the '90s. It was the generation of the underground."

He continued, "Even though I have a lot of mainstream appeal, I come from the underground, and I just wanted to give back to that. That's why I was really strategic on who I picked to be in the line-up as far as artists and features go. With Joey Bada$$ and Action Bronson and Danny Brown, they're from the underground. Yelawolf, he's really underrated if you ask me, I feel like he's one of the best lyricists of today. I think everyone on that track has value for our generation."
