Luzelena Mendoza, of Portland's Y La Bamba, seems to mostly split her time between evoking cracked and worn '30s lullabies and embracing the freak folk scene inhabited by the likes of Devendra Banhart. It's a fairly beguiling mix, and a bold one at that. If there were a chink anywhere to be found in Y La Bamba, the first place anyone would look would be Mendoza's voice - but her vocals, it must be said, are gorgeous. That's the whole game. Y La Bamba's victory lap is in the chances they take with exploring world sounds and chamber music, which lends a little color to the proceedings, and helps to differentiate Mendoza from fellow '30s devotees like Jolie Holland. Above all, a kind of elegance shines through in Mendoza's music. And elegance, you can't fake.
