Esoteric, bewitching, and gothically flamboyant—that's right, we're talking about rock en español trailblazers Santa Sabina. Hailing from Mexico City in the late ‘80s, these experimental mavericks stunned onlookers with their hypnotic onstage theatrics and their fiery frontwoman Rita Guerrero, whose operatic vocals could very nearly bring a crowd to its knees. Armed with a sitar, saxophone, and cello, these unconventional rockers left behind a rich musical legacy after Guerrero's death in 2011.
