One of of the most anticipated tracks off of Long.Live.A$AP features a who’s who of some of the hottest young rappers in the game right now. “1Train” consists of six straight minutes of fiery bars from the likes of A$AP Rocky, Kendrick Lamar, Danny Brown, Big K.R.I.T., Action Bronson, Yelawolf and Joey Bada$$. The song wouldn’t be quite complete though without the immaculate production courtesy of Hit-Boy. For those still getting accustomed to some of the names on this list, the song serves as a proper introduction to the future of rap music. This outstanding single is just another hit from the Harlem emcee who’s been churning them out left and right in preparation for his debut album, set to drop on January 15th.
