Battle rap has evolved into theater. If you think you can just get up there and rap cool and win then you have another thing coming. If you’re not in tuned with the culture you won’t stand a chance. What Cass was doing in the early 2000s was fire for that time but it’s not advanced enough.
Take this battle for instance
Watch how K-Shine used Geechi round ending slogan against him and jumped straight on his head. Look at the energy, hand movements, and performance of each bar. This is not just two dudes trading bars anymore. Plus battle rap has so many inside bars that people don’t even get unless you follow battle rap. A regular viewer would hear that coffee mug line and wonder why it got a reaction. Not knowing Geechi home girl is named coffee brown and standing in the crowd.
