Found this on Radio LaChusma’s MySpace:

El Paso has a unique ability to find brotherhood in music. There is an El Paso Sound, a musical common denominator that unites the city. The city has a peculiar nostalgia—as it stands at a crossroads on the border—for the musics of the U.S. and Mexico. That nostalgia finds its expression in the music played early in the career of one Steve Crosno. Crosno managed to recognize that people in El Paso wanted to hear a mixture of blues, norteño, pop and carribean music. El Paso being the place where all those different sounds jumble up together. So he created a unique playlist of doo-wop and early rock’n'roll that took the region by storm.
