The fact that the MuzikMafia did not promote a single musical idiom might seem like a disqualifying factor in the industry. Their unifying trait was its diversity. The roster included artists who specialized in blues, rock, pop, rap, country, bluegrass, gospel, R&B, and soul that, collectively, are representative of Nashville’s rich history of musical diversity and the city’s current identification as “Music City, U.S.A.” The rapid growth in popularity of the MuzikMafia was the result of its two breakout acts, Big & Rich and Gretchen Wilson, who celebrated combined record sales of approximately five million units just from May through December 2004.
