The world is mourning today as we all pay tribute to the late Phife Dawg, the A Tribe Called Quest member who passed away last night at the age of 46. In his honor, rapper Mac Miller has released a tribute to the 5 Foot Assassin that pulls some lyrics from Tribe's "1nce Again" over some soft, melodic production from Mac. "i don't even know what to do right now. this is crazy," Mac said on Twitter.The track is appropriately called "5 Foot Assassin: Larry Fisherman Tribute." Stream it below.RIP Phife.
