Bronson's look, charisma, and appeal could impress me if I was an A&R. However his inability to wirte a chorus to save his life, and the one note lane he puts himself in, would make me stay away.
Some guys audition for major labels. You can really tell Troy Ave is making his case right now. His album has dope production, some solid choruses and musical variety. Likewise a few years ago any A&R or label head could tell that Drake, Cole, Kendrick, etc were making a case for getting signed; all three had legit mixtape songs that sounded like they could get radio play.
Whereas when I listen to Bronson, Curren$y, Exquire, etc I hear dudes who have very little interest in constructing songs. They get a beat, rap over it, boom that's it. No chorus no nothing. I'm not knocking that, I love Bronson, Roc Marci, Curren$y and others who do this. The point is that they aren't marketable mainstream wise, and haven't demonstrated an ability to make a radio track. Bronson gets radio play on Hot97 but honestly that seems more of the station making a point ("we play NY rap if it fits a certain criteria"). Strictly 4 My Jeeps didn't sound like a radio song to me, the chorus is bad and the beat is a rip off.
Dudes need to realize that people go to shows to have fun. It's easier to have a dope live song if it has a simple chorus people can chant. Roc Marci has really put himself in a box IMO because his music simply wouldn't work live. Spitta, Bronson, etc all have live shows without choruses, I'm just saying they'd be liver with big records. Think CREAM.
