Sounds normally associated with Los Angeles: The whirl of helicopters, the shrill of police sirens, the blaring of car horns. But that's all hype and Hollywood. There is another sound that fills the streets of this sprawling urban Mecca and it's an amalgamation of hip-shaking Latin rhythms, bass-heavy hip-hop beats, streetwise rock riffs, and funky soul grooves. Even a gorgeous redirection of wind can be heard weaving its way through the organized chaos, calming its paroxysmal energy. Collectively, that sound is called Fredalba.
