1. Run the Jewels, 'Run the Jewels 2'
The second album from hip-hop's knottiest insult comics expands the emotional palate of their previous collaborations — coming with a protest song for Ferguson and New York ("Early") and a ballad that flips rap's drug tales into a struggle with guilt ("Crown"). But the appeal is still in their giddy disses, labyrinthine boasts, alliteration, bravado, alpha male antics — basically the stuff that Killer Mike and El-P enjoyed about rap in 1989. It's a throwback in that it cares about set-ups, punchlines and feats of skill — but its distorted explosions of synth noise keep an eye to the future, maintaining a brand "where destruction's the number one commitment."
