It’s hard to tell the story of Latin hip-hop without Kid Frost. Born Arturo R. Molina Jr. in 1964 in L.A., he frequently draws on his Mexican ancestry, infusing his songs with bursts of Spanish and soundscapes derived from his upbringing. On “La Raza,” a cut from his 1990 debut album, Hispanic Causing Panic, he lets loose a career-defining statement of purpose: “Chicano and I’m Brown and I’m proud.” Over the years, Frost has continued to imbue tracks with his heritage, like the jazz soundbed on “Mi Vida Loca” and the jumpy piano melodies from south of the border on “Mamacita.” The MC’s West Coast roots shine through, too: On 2003’s “You’re No Good,” he tells street tales over a somber G-funk instrumental. With effortless cool and formidable skill, Kid Frost is a foundational force in the Latin rap tradition.
