Rubén Urrutia (born May 7, 1967), better known as Ruben DJ, is a Puerto Rican former rap star who became famous in the late 1980s with the hit song "La Escuela".
He said in an interview "I quit my job, had problems at home, I spent six months promoting all over Puerto Rico with the same cap, the same pants; I lost my car, I had a Datsun that was all junk.
At the moment, underground rap music was becoming popular in the island and Rubén's song, along with Vico C, Brewley MC, and others, is considered to be among the most influential ones for the genre.
"La Escuela" was a motivational song, encouraging children to stay in school, which broadened its appeal to the general public.
Ruben DJ himself became a celebrity nationwide in Puerto Rico, appearing on the covers of magazines, television shows, and newspapers.
