I think it all depends on what you consider "blowing up". The "From the Hood" video has done great for it being independent. It's currently on MTV Jamz, Music Choice, and a few other video programs.
As far as "blowing up" and getting a major deal, a major deal most of the times is not a great deal. How many people can you list who had major deals, and were shelved... Even major artists! Many people on majors are trying to be independent. When your on a major, sure you have money and major promotion behind you. But, you also have other people running your career and you can't be the creative artist that you started off as.
Our artist (Jacka, Traxamillion, Demolition Men) have blown up! Try looking at it in a different perspective. Right now, there are MILLIONS of people trying to do music. Everyone raps, sings, produces. Competition is FIERCE and equally watered down. Reality is that only a handful of people will get that "big break"..
Being independent, our artist are doing what they want to do, however they want to do it. They're "FREE" to be creative, and grow. Every year, they gain thousands of new fans which generate more great money. They also get national and international attention. All of our artist are definitely bigger artists then they've ever been.
Success isn't about "blowing up".. It's about accomplishments! Our artist have definitely accomplished a lot, with many more accomplishments coming..
