You can call Kool G Rap hip-hop's most underrated legend. Having initially made his mark in the golden era alongside DJ Polo and under the production watch of Marley Marl, the MC from Corona hit the '90s hard with a series of ridiculously hardcore albums that showcased his furious gangsta flows and ability to document the shady underbelly of New York City in cinematic terms. The Kool Genius of Rap might not be a commercial chart-topper, but his reputation is gold among the rappers he's influenced like Nas, Big Pun, and Eminem.
