María José had her first professional experience in the world of music in the Kabah group, of which she was a part until their separation in 2005. Two years later, she released her first solo album titled María José, with ten songs that cover genres such as pop, dance-hall and hip-hop, and have the participation of Plastilina Mosh and Sergio, ex-Kabah.

The first single “Who Are You” (featuring Trey Songz) marked a great start to his solo career, followed by the single “I Was Wrong”. Both hit Top 15 radio. Her relevance on the national scene became clear when she was invited as the opening act of the concert that Gwen Stefani offered at El Palacio de los Deportes in 2007. Two years later, in 2009, she was chosen by Rihanna to open her show in the same venue.
