2003 seems to be a sweet spot in Calexico's development. They are still firmly entrenched in a regional sound, with nods to their earlier existence as the band providing the soundtrack to imaginary Westerns. But by 2003 their sonic palette has widened, showing more jazz & electronic elements. A bit of pop has been added to the mix as well. They sound a bit like Los Lobos' younger brothers, less dependent on blues structures, but clearly from the same neighborhood.
