Genre crossovers are a tricky thing.

Many bands have bolstered the genre: Groups like Beastie Boys, Death Grips, Twenty One Pilots, and Rage Against the Machine have given their own hip-hop spin to traditional alternative music, while rappers like Post Malone and Lil Peep have used rock-inspired beats to varying degrees of success. Most exciting of all, though, is when rock bands, who are strictly known for rock, team up with rappers, who are strictly known for rap.
