About Alaina Castillo — musician

Alaina Castillo is a Los Angeles-based musician whose Instagram blends emotionally resonant new music, singing content, and polished beauty/fashion storytelling. She’s a strong fit for campaigns seeking an artist with an engaged audience, a clear visual identity, and authentic creator-style content that naturally integrates product moments.


Why you should sponsor me for your next influencer campaign?

 Houston native Alaina Castillo first found fame with her online renditions of popular songs before making the jump into the pop world with the release of her 2019 debut EP, the bilingual Antisocial Butterfly. In 2020, she released another EP, the voicenotes, with her vocal delivery and alternative take on pop eliciting comparisons to contemporaries Billie Eilish and Ariana Grande . Later that year, she issued the singles "Tonight," "Párate," and "Wishlist." The rising pop star is coming off a breakout year that propelled her name into the head of the 2021 class, earning the coveted spot of Spotify’s first-ever US RADAR artist, being named one of Billboard’s Latin Artists to Watch, and landing a spot on NME Essential Emerging Artist list.
