Luzelena Mendoza's captivating voice is the centerpiece of Y La Bamba's sound. But the rugged-looking choir boys behind her obviously find joy in blending their voices into rich vocal harmonies. They strum and pluck, but mostly they close their eyes and throw their heads back in gentle yet full-throated singing. Based out of Portland, Oregon, the band's dark, minimalistic Mexican-inspired experimental folk songs engage the listener in a realm of the dreamy solitude of a very old soul.
