Music producer Chris Strachwitz began collecting recordings of Mexican and Mexican-American music nearly six decades ago, gathering the music of the southwestern United States and Mexico. The Strachwitz Frontera Collection of Mexican and Mexican American Recordings is now the world’s largest and most complete collection of Mexican American vernacular music, containing some 150,000 recordings from small regional recording labels. Now you can learn about the sounds of Mexican American culture and the rich artistic landscape of the borderlands at the UCLA Frontera Web site, which has been supported by four NEH grants to the Arhoolie Foundation since 2006. The Frontera project, a collaboration between the Arhoolie Foundation, the UCLA Digital Library, and the UCLA Chicano Studies Research Center, has now preserved over 100,000 recordings from 33-rpm, 78-rpm, and 45-rpm discs as well as cassettes, LPs, and original reel-to-reel masters.
