Felipe Coronel better known as Immortal Technique, is a hip-hop MC and political activist. Most of his lyrics focus on socio-political issues. The views expressed in his lyrics are largely a mixture of left-wing political commentary on issues such as poverty, religion, and racism.

Although he has been offered a deal with at least one major music label, he has never signed to any. Immortal Technique has also voiced a desire to keep control over his production, and has made statements in his music that he is very aware that it is record companies, not the artists themselves, who profit the most from mass production and marketing of music.

He releases his music on, and is also the Vice President of, Viper Records.

Compiling multiple assault charges in New York State and in other states eventually caught up to the uncompromisingly hardheaded actions of one Immortal Technique. He faced several charges for Aggravated Assault in the tri-state area. Realizing his inevitable incarceration, Technique began to prolifically write down his ideas about what he had lived and seen in the struggle back at home in relation to his visits back to his native land. He came to embrace his African roots that stemmed from his grandfather and understood the nature of racism and ignorance in its role in Latino culture, separating oppressed peoples and keeping them divided. He also began to study in depth about the Revolutionary ideas that had caused a history of uprising in the indigenous community of his Native South America.
