These Mexico-born, Dublin-based acoustic buskers made their name by flamenco-fying Metallica and Zeppelin songs, and their latest set was mixed by old thrash hand Colin Richardson. So it’s no shock that 11:11‘s most affecting moments — the title track and “Logos” — come when the duo’s time signatures slither into a stalagmite-strewn prog-metal cave. They also pay alleged homage to Hendrix and Dimebag Darrell, the latter in a Middle Eastern-leaning collaboration with Testament’s Alex Skolnick. But mainly they noodle through indeterminate world-music jams that’d feel equally ignorable at mud festivals and at ethnic restaurants.
