Alejandra Villarreal Vélez is a Mexican musician best known as the bassist, backing vocalist, and pianist for the rock band The Warning. Born in Monterrey, she stands as one of the most technically proficient young bassists in modern rock.

As the youngest member of the trio, Alejandra balances the role of the group's rhythmic anchor while contributing to their signature sound through piano and harmonies.

She currently continues to lead the group's musical direction alongside her sisters. [edit]

Alejandra Villarreal Vélez was born on December 13, 2004, in Monterrey, Nuevo León, Mexico. She grew up in a household where music was not just a hobby but a daily language. Her father, an amateur musician, recognized her early interest in rhythm and provided her with instruments when she was still quite young. Unlike many professional musicians who attend prestigious conservatories, Alejandra and her sisters Danna and Paulette were largely self-taught. They learned by ear, relying on online tutorials and listening intently to their favorite bands.

The sisters spent their childhoods writing songs together in their family home, often practicing late into the night. By 2013, at the age of eight, Alejandra had already begun playing bass seriously. The trio started uploading cover versions of popular rock songs to YouTube that same year. These early videos featured complex arrangements of tracks by Metallica, Foo Fighters, and Linkin Park. The channel quickly gained traction, with fans captivated by the technical skill displayed by three teenage girls. This period laid the foundation for their career before they ever stepped onto a professional stage or signed a record deal. [edit]

The official formation of The Warning occurred in 2013 when the sisters decided to pursue music professionally. Alejandra evolved from a hobbyist into a professional bassist as the band began to gain traction. Their breakthrough came with a viral cover of "Enter Sandman," which garnered significant attention from major media outlets and established them as serious musicians rather than novelty acts. In 2016, they released their debut studio album No Way Out, produced by Dave Fortman. This marked their transition from internet sensations to recording artists with original material.

Subsequent releases showcased their growth as songwriters. The 2018 album Polaris received critical acclaim for its heavy riffs and emotional depth. During the global pandemic in 2020 and 2021, the band maintained a strong connection with their fanbase through acoustic sessions and live streams. They also signed with Universal Music Group, expanding their reach significantly. In 2022, they released Seismic Shift, further solidifying their status as a leading force in the rock genre.

By 2023 and 2024, The Warning embarked on extensive world tours, supporting major acts like Muse and Royal Blood. In 2024, they were featured in Guitar World for their innovative approach to rock music, emphasizing the interplay between the three instruments rather than relying on guitar solos. In 2025, the band launched their "Keep Me Fed" world tour, which included 19 dates across the U.S. and international stops. The tour was a massive success, selling out venues and drawing large crowds. In February 2026, they released their English debut single "Love to Be Loved" in collaboration with Carín León. Later that year, they released "Tu Corazón" with PNAU. In May 2026, it was announced that The Warning had signed with United Talent Agency (UTA), marking a significant step in their management and representation. [edit]

Her stage presence is energetic and confident, often characterized by her dynamic bass playing and interaction with her sisters and the audience. Her aesthetic is practical yet stylish, reflecting her personality as a dedicated musician. Media perception focuses heavily on her technical proficiency and the rarity of a female bassist commanding such respect in the rock genre at such a young age. [edit]
