Everyone knows that rappers 50 Cent, Rick Ross and Mac Miller are hugely popular (and wealthy). But it might come as a surprise that Tech N9ne ranks right up there with them; Forbes magazine just listed him ahead of the aforementioned rappers in a recent “Hip Hop Cash Kings” article. Tech N9ne, whose career dates back to the early 2000s, tours some 200 days out of the year. The Independent Grind Tour 2014 follows the Something Else Tour 2013, which came as Tech N9ne had the biggest year of his career thanks to the popularity of his hit song “Fragile,” featuring Kendrick Lamar, ¡Mayday! and Kendall Morgan.
