Trading richly orchestrated boom-bap for wracked robotic crooning, Kanye's radical 2008 album brought emotional devastation to hip-hop, freeing young MCs like Drake to explore a thousand shades of vulnerability. By pushing a newly melodic flow through woozy layers of Auto-Tune, he permanently transformed the art of rhyme, leading to acts of disorienting mic vandalism like Future's digitally mangled flow, and Yeezy's computerized soul eventually filtered into sounds as distinct as Bon Iver's experimental indie folk and SZA's atmospheric R&B.
