In 2012, Problem really broke through by appearing on E-40's "Function" and Wiz Khalifa's Cabin Fever 2. Those were two of his biggest looks but certainly not even a quarter of his grind as he dropped Welcome To Mollywood 1 and 2, collaborated with the likes of Omarion, Freddie Gibbs, Snoop Dogg and others, and tore up clubs in California. 

As he works on his next project, he links up with fellow Diamond Lane Music Group artist Bad Lucc on a dance ready cut called "Twerk." It's a nice taste of what Problem can do in terms of club music. The record is highly infectious.
