Ask him about his soul train performance he did when he was like 17. He had a mean mug the entire performance and even when talking to don Cornelius. Excellent performance and he destroyed it.
Ask him about how his flow changed...in his early days, he would ride beats and DESTROY them...ie Headbanger, Time for some aksion. He then slowed his flow we down and didn't really ride beats. Just kinda became a slower punchline rapper which is a damn shame.
Tell him we need some HARD ASS DRIVING BEATS that he can truly bust and ride the goddamn beat with some rhythm!
Ask him if Muddy Waters 2 is gonna be true sequel stylistically, or is he merely following the trend of all these rappers choosing their most acclaimed album and doing "pt. 2" just to ride the legendary name as a gimmick and then the album sucks.
You can word those more eloquently, but get those points across and let him know that fans feel played like punks when they do those gimmicks and its NOTHING like the OG album.
Also, point out since he is Indie, he should really cater to his core audience that loved Muddy Waters. If he does that, his long time fans will purchase off GP. If he's hopping on trends and not making the music his core fans liked on Muddy Waters, IT WONT SELL AT ALL.
