"Alaina Castillo is making it clear to the world that the pop crown is within reach" – Ones To Watch Houston-born bilingual singer-songwriter Alaina Castillo releases her newest single “call me when you’re lonely”, the start of a new era for Alaina. On the track, Alaina puts her stunning vocals front and center, relaying what being a “sad girl” is for her. The rising pop star is coming off a breakout year that propelled her name into the head of the 2021 class, being named one of Billboard’s Latin Artists to Watch, and landing a spot on NME Essential Emerging Artist list. Alaina has so far also racked up over 160M audio and video streams, nurtured a fan base of nearly 2M followers on TikTok and delivered stunning performances on Seth Meyers and the Latin AMAs. These are just a few of the many reasons Wonderland Mag thinks she’s “about to hit big time very soon” and we could not agree more!
