Impact is tough to judge now because has never been more disposable. Is the KD run impressive? Sure, but it's mainly to appease the hardcore fan. Beyond that, it's tough to say who's really making lasting impact (damn near any suggestion would be wrong)
not that Jim Jones needs to be mentioned (I get what
@Piff Perkins is saying though) but Jim's 2nd wind has mostly been really good and I don't think it's impacted the culture, but it was resonated with his fans and for the demo that appreciates rappers in their 40s making meaningful music.
Nas just sold out Madison Square Garden. And he did it with the KINGS DISEASE trilogy. Not Illmatic. Not It Was Written. Not I Am. Not Stillmatic.
Nas is a legacy act. He could drop Black Girl Lost pt. 3-15 and still sell out MSG.
