“1 Train,” the most hotly anticipated track from A$AP Rocky’s forthcoming Long. Live. A$AP., dropped today, and the result–a six-minute posse cut featuring Kendrick Lamar, Danny Brown, Action Bronson, Yelawolf, Big K.R.I.T., and Joey Bada$$–mostly delivers on its promise. It isn’t quite on the level of “The Last Huzzah” as far as capturing the current “underground” zeitgeist, but its cast of players is undeniable and the uncharacteristically laid back, string-laden Hit Boy beat delivers.

Somewhat surprisingly, Yelawolf is the man of the hour here, going in fourth and breaking the track wide open with his stop-start, syncopated flow.
