The lead singer is a Chabad Rabbi and the band is super heavy. Atzmus also hails from Argentina. This track, Ciudad Del Luz, had some good traction a couple years back when it was first released but now the band seems to have gone poof! Their web site has been taken over by spammers or something and they don’t seem to have performed in two years according to their Facebook page, but whatever. The track still rocks and is good for a bolt of adrenaline whenever you need it… Well, that’s how it works for me. And I don’t even speak Spanish! You can get more info from their record label page (Spanish) r just keep hitting repeat on this video.
