Early on in his discography, A$AP Rocky set himself apart for a number of reasons, but his impeccable beat selection was always part of the conversation. From Clams Casino to Kanye West, Rocky knows when he's got some killer production on his hands. One of the most exciting elements of so much of his music, though, is how he's found a way to rap over any number of genres and make it sound great. Even better, he's working with producers keen to experiment and really challenge listeners.

With his third studio album, TESTING, on the horizon, Rocky is tapping into his adventurous nature once again. So we decided to revisit some of Rocky's most interesting and left-field choices, from his debut mixtape to the Moby-featuring "A$AP Forever."
