Based out of Mexico City, the closest genre classification I can come up with is Spanish punk-polka. I could seriously leave it at that, but then Hugh would probably yell at me.
Their Myspace describes their sound as a range from â€œeuphoric polkas, melancholic waltzes to punk, rock and passages of classical musicâ€. They also come highly recommended by Denise Petersen (the wife of Erik Petersen, i.e. Mischief Brew), and I seem to have a thing for any bands distributed by, or even just vaguely associated with Fistolo Records.
They also have some fine klezmer clarinet, and a penchant for instrumentals. As such, Hugh will probably hate them. They do have at least one member hailing from Oregon, though.
