Since 1999, Shady Records—the imprint founded by rhyme superstar Eminem and manager Paul Rosenberg—has released a wide array of hip-hop music: the multi-platinum hooks of 50 Cent, the dizzying displays of supergroup Slaughterhouse, the country-fried speed trials of Yelawolf, the new-classic grit of the Griselda collective and, of course, the bars upon which Eminem has cemented the legacy of his bad attitude and twisting tongue. And as broad as the sounds are, all Shady Records artists share a commitment to rap's battle-ready principles of gymnastic lyrical feats.
