Something always draws these aging Argentinean punks back together. You can hear the peculiar chemistry between men who have been playing together for a quarter of a century -- and not just in the shirt-ripping assault of the title track. It's a credit to Los Cadis that the best songs here aren't covers and do-overs (good as they are), but originals: "Nosotros Egoistas," in honor of their late percussionist, Toto Rotblat; "Hoy"; and "El Fin Del Amor." Ska-punk will always be the group's default setting, but marry it with strong melodies and real sentiment and the music transcends its genre.
