Hermanos Gutiérrez at Popejoy Hall

The Swiss-Ecuadorian brothers Estevan and Alejandro Gutiérrez play a kind of wordless, sun-bleached guitar music that sits somewhere between spaghetti western scores and Andean folk, and Popejoy’s acoustics will do it genuine favors. Y La Bamba, Luz Elena Mendoza’s emotionally direct project, is a real opening act and not an afterthought. Popejoy is a seated hall, so if you want to move around, adjust expectations accordingly.
