Chicano rap is a unique style of hip hop music which started with Kid Frost, who saw some mainstream exposure in the early 1990s. While Mellow Man Ace was the first mainstream rapper to use Spanglish, Frost's song "La Raza" paved the way for its use in American hip hop. Chicano rap tends to discuss themes of importance to young urban Chicanos. Some of today's Chicano artists include A.L.T., Lil Rob, Psycho Realm, Baby Bash, Serio, A Lighter Shade of Brown, and Funky Aztecs Sir Dyno, and Choosey.
