Kase.O

Javier Ibarra Ramos (Zaragoza, 1 March 1980), better known by his stage name Kase.O, is a Spanish rapper, songwriter, producer and entrepreneur, and a member of the Spanish rap group Violadores del Verso alongside fellow rappers SHO-HAI and Lírico, and DJ R de Rumba.

He is regularly considered by the community and the media to be one of the best-known Spanish-language rappers. He has been active from 1993 to the present day, serving as an icon and benchmark for rap in Spanish.

Throughout his career, Kase.O released up to seven studio albums with Violadores del Verso between 1998 and 2006.

Then, in 2011, he released his solo work Kase.O Jazz Magnetism, an album blending hip hop and jazz, remasterising some of the artist's hits and creating new ones alongside the band Jazz Magnetism. In 2015, he released "Previo", a preview of his LP which was due out the following year. In 2016, he released what was his biggest solo success, "El Círculo", which received multiple nominations including at the Latin Grammys, proved a revelation for rap and won a gold disc award, an accolade previously received with Violadores del Verso.

Kase.O was placed second on the list of the "50 greatest rappers in the history of Spanish-language rap", published by the US magazine Rolling Stone.

In late December 2024, he was awarded the Gold Medal for Merit in the Fine Arts, approved by the Council of Ministers upon a proposal from the Spanish Minister of Culture.
