The Story
Cabo San Lucas'
Cabo San Lucas'
Premier Family Band
Kids Monsters is five siblings from the Castolo family — Genessis, Nickeit, Nirvana, Osiris, and Ramses — originally from Ensenada, Baja California, and based in Cabo San Lucas since 2016. With 15+ years performing together, they deliver a high-energy live show spanning pop, rock, R&B, Latin, jazz, cumbia, and reggaetón — fully bilingual in English and Spanish.
What sets Kids Monsters apart is the chemistry of a family who has played together their entire lives — something no rehearsal schedule can manufacture. They're the preferred entertainment act at Los Cabos' top resorts, including Esperanza Resort, Chileno Bay, One&Only Palmilla, Paradisus Los Cabos, Hotel Marquis, and Grand Velas, and are available in acoustic duo/trio or full five-piece electric format — for Optimo Entertainment clients planning a destination wedding or an international event.
