Volcán, an 11-member ensemble hailing from San Antonio, Tejas, embodies Latinx unity through their joyful, shapeshifting sound, blending psych-rock-infused cumbia, salsa, calypso, and more into a funky, catchy, and danceable mezcla that rises like a sonic dynamo from la selva, inviting listeners to transcendence with its mystical atomic heat.
