Scene from the movie: Trustus Jones guaranteeing he'd sign the guys right after they get thrown into the dumpsters behind Gusto's club
Real life examples: Kreayshawn; Trinidad Jame$
After being thrown out of the club and into the trash, CB4 could've disappeared and no one would've cared. But Trustus Jones saw something in them. (That something turned out to be built on nothing, but alas.) In the pre-Internet era, record labels offered new artists a bunch of things: credibility, visibility, and—most importantly—distribution. But then everything fell apart.
MP3s begat blogs, blogs begat Mac Miller, he and people like Macklemore showed you can be a number-one artist independently. Now, the biggest difference between doing it on your own or having a building behind you is the amount of money it takes to sign the paperwork. So, Drake could've been independent. Drake almost existed as an entirely independent artist! But then he signed a seven-figure deal and never had to worry again. Great! He's made Universal/Motown/YMCMB much more money than the initial million dollars he was offered, and because of their work, they've made him a lot, too. Very solid investment; very shrewd.
But not every artist is going to be Drake. Not every scene is going to make money. There are far more Jerkin' movements than TDE's. Just look at the land grab in Chicago after Chief Keef exploded onto the scene: Lil Reese and Lil Durk were immediately signed to Def Jam, only for Reese to get dropped soon after video surfaced of him punching a girl. Lil Durk—associated with Coke Boys—still hasn't released an album and hasn't quite captured the industry's attention as some probably thought he would.
