About the Band

Cabo's Most Versatile
Live Band

Kids Monsters is a professional live band based in Cabo San Lucas, booked for Cabo weddings, destination weddings, corporate parties and festivals across Mexico. Originally from Ensenada, Baja California, this family of musicians has spent 15+ years developing a refined, versatile sound built entirely for live performance.

Every set is built live — bilingual, adaptable, and charged with a family chemistry no hired band can replicate. From cocktail hour elegance to dance floor fire, they read the room and deliver every time.

More than music — an experience.

Quick Answers

Frequently Asked Questions

Everything you need to know before booking Cabo's premier live band.

How far in advance should I book Kids Monsters?

We recommend booking 3–6 months in advance for weddings and major events, especially during peak season (November–April). For corporate events and smaller gatherings, 4–8 weeks is typically sufficient. Contact us to check availability for your date.

Do you perform in both English and Spanish?

Yes — Kids Monsters is a fully bilingual band. We build custom setlists in both languages to perfectly match your audience, venue and event style. No other band in Los Cabos does this with the same fluency and versatility.

Can you travel outside of Cabo San Lucas?

Absolutely. We are based in Cabo San Lucas but perform throughout Baja California Sur, across Mexico, and are available for destination events internationally. Travel and logistics are factored into our custom quotes.

Do you perform at charity events and galas?

Yes — we are proud supporters of the Los Cabos community and regularly perform at charity galas, fundraisers and benefit concerts. Contact us to discuss availability and charity rates for your cause.

What performance formats do you offer?

We offer acoustic duo/trio sets for ceremonies and cocktail hours, and full five-piece electric sets for receptions, galas and festivals. Custom multi-phase formats are available — tell us your event timeline and we will design the perfect performance.
