After celebrating their 40th anniversary with the live album "Disconnected in New York City," Los Lobos return with "Gates of Gold," their first studio album since 2010's "Tin Can Trust." "We're a Mexican American band, and no word describes America like immigrant," says Los Lobos wordsmith Louie Perez, describing the new release. "So it's perhaps natural that the songs we create celebrate America in this way." It's been a long time since Los Lobos have played Ann Arbor, and this is a rare concert opportunity indeed.
