Detroit street rap was never relevant in hip-hop, Blade Icewood a Detroit legend and most people never heard of him.You mean a resurgence?
We don't count the drill movement as a Chicago resurgence because the previous Chicago rappers didn't sound anything like them, sonically or subject matter wise.
When I say Detroit rap might get its moment I mean Detroit street rap. Not Dilla, Black Milk, Big Sean, Eminem.
